"With this car (Datsun 510) coming on board I hope we get some better tyres from Slot.it for small diameter wheels. Need F22 and N22 for the 14.3mm diameter wheels. I know you can use the PT 1207F22 but they need a lot of sanding to get the diameter down."

My search for alternatives to Slot.It tyres started shortly after purchasing my first Slot.It DTM car. Out of the box, there was hardly track clearance provided by the (I believe) PT1228C1 tyres mounted on 15.8 rims. This situation seemed to occur across the whole range of DTM cars and one of the clubs I race with had to change its track clearance rules, or force all competitors to replace their standard tyres.

Case 1 Somehow I managed to inherit a pair of Thunderslot tyres in a job-lot given to me, and the diameter  suggests they came from a Shelby Mustang. They fitted nicely on my Mercedes DTM's standard 15.8 rims and with just a little true-ing they were a good fit in terms of clearance under the wheel arches and providing clearance between the chassis and the track.

Inspired by this I recently purchased a packet of Thunderslot TYM004R 'muscle car slick racing rear tyres' which measure 9.70 x 19.60. I have yet to mount them on wheels.

Case 2 Some months ago I bought a pair of BRM/Revoslot tyres 'on spec'. I can't recall the part number but they may have been intended for use with 1:24 scale BRM sedans. However, fitted to Slot.it WH1190-AL flanged rims they too proved useful for my Mercedes DTM car.

Last week I bought a packet of Revoslot RS-202S 22 shore tyres. While these have probably been designed for the larger Revo wheels they are a snug fit for the WH1190-AL Slot.It flanged rims. Mounted on the rims they measure just over 20 mm in diameter before true-ing.

Given my positive experience of tyres fitted to all of my  Revoslot GT2 and LMP cars I'm fairly sure these will provide good grip and outlast other brands.

Case 3 Having decided to experiment with a 3:32 rear axle set-up in my Revoslot Escort obviously I needed small diameter wheels and tyres to avoid rubbing on the wheel arches of the small sedan.

I had a set of Policar W14308015A 14.3mm rims from a 'conversion kit' and found that they matched up nicely with NSR classic treaded tyres designed for the smaller Slot.It sports cars e.g. Ferrari 312PB and Alfa T33. Trued just enough to remove the tread pattern these were a good fit for the Revoslot Escort.

Conclusion? If Slot.It doesn't have the tyres you're looking for then perhaps you need to consider other options.

All N series are gone for good. F series are pigs to true, and the 1207 mould size isn’t really intended for that small rim, it is for 15.8mm rims.
You will find that 1170 E series a decent option. It works well on semi-gloss and is fairly easy to true. See it in the top line of the tyre chart wheel-fit table below.

The PT19 is a good low profile zero grip for the fronts

 

Useful...so copied here too

"Inspired by this I recently purchased a packet of Thunderslot TYM004R 'muscle car slick racing rear tyres' which measure 9.70 x 19.60. I have yet to mount them on wheels."

In my opening post for this topic I suggested Thunderslot TYM004R tyres as a possible alternative for the some of the Slot.It items that are no longer available. My enthusiasm was driven by a positive experience with a pair of Thunderslot tyres given to me by a friend.

Yesterday I mounted a set of the TYM004R tyres that I bought and was surprised, and disappointed, that the tyres had developed some cracks in the sidewalls. I'm fairly sure that I did not stretch the tyres too much to fit on the rims, nor did I feel that the 'glue' used, "Sally Hansen's Hard As Nails", would have had an adverse reaction with the rubber. I have used "Hard As Nails" regularly with other tyres and have not had a splitting problem - including the pair of Thunderslot tyres I was given.

The material used in the TYM004Rs seems to be different than the set I was given so it but it is unclear whether this may be the cause of the splitting. In the meantime I have tried to patch the cracked sidewalls with superglue to try and prevent the cracks from spreading.

I had thought of them but glad you gave it a try first as I won’t bother. 

[big dennis]

For your information Vinno, and others ...

I have mounted my remaining pair of Thunderslot  TYM004R tyres to smaller rims (14 mm) and glued with brush-on superglue, and I'm pleased to say that there hasn't been any splitting or other adverse effect. The OD before true-ing is 19 mm.

My attempt to patch the cracks in the first set was a dismal failure ... the cracks spread further, extending into the contact patch area.

I'll provide updates when I've had a chance to run the Thunderslots, and Revolot RS-202S, on the local track.

Hi Big Dennis and VINNO.

I bought several packets of the TS Camaro tyres for replacement of Scaly rubber tyres on NASCAR's and distributed them to our group. They are a reasonable fit but had to be glued and trued as NASCAR wheels have a very narrow centre ridge which distorts them slightly. My NASCAR appears to be going quite well. Agree not the same compound as normal TS tyres but they are just big enough to provide some ground clearance for otherwise standard NASCARS. Traditionally we ran Scaly rubber tyres which were getting hard to source as a National class to 2016. Early in New Year we decided resurrect but allow any rear tyres. Other cars have had a combination of silicone, urethane and rubber tyres. The TS Camaro tyres are my attempt to limit to a standard tyre.

Hope this is of some interest. Regards Charles Le Breton (charlesx)

I like standard TS 002R tyres, very similar to original NSR Supergrips. 

I've acquired a pack of TYR005R tyres that are designed for Carrera track but I'll be driving on a wood track. They're not easy to true, similar to NSR Extremes to grind on a hudy but trued easier on a flat plate type truer. I'm hoping they're going to perform like original NSR Ultras.

I've yet to see a set of Revo tyres that don't start to ball-up under hard racing conditions (on a wood track)

Never had a problem with Revo 30 and 25 shore,but the 22 s do ball up a bit once there is a lot of rubber down on our routed tracks.

[big dennis]

Kevan,

I think that with time and usage most tyres,  not just Revoslots,  will show some form of degradation. As our races in Tasmania usually consist of only 3 or 4, 3-minute heats any 'balling-up' can usually be rectified before the next event.

Perhaps two of our Auslot members who were on the podium at the recent Australian Revoslot Championships could offer their thoughts, having raced on a 6-lane track in heats, semis and a final that had 5-minute stints.

We race similar, mainly 3 mins but sometimes longer. Standard Revo 30s are my favourite but have recently tried the new g25's which suffer the same problems as all the other manufacturers g25's

Track surface and amount of rubber build up vary so much from club to club, and even night to night that tyre choice becomes what works on your track on that particular race.

Yep - at the last race meeting - it paid off to be in later heats the track got faster as the heats progressed (18 racers) 

[john lydon]

Love the chat, but so disconsolate the slot it N's have been deleted, Were close to unbeatable on any timber track surface from lap 1, relatively easy to true & glue, didn't ball up and had very good wear life. RIP

Hi John. Yes agree re N22's. Fantastic tyre. Why were they discontinued???

Have you tried replacement G25 though. Suggest you do.

Hi Charles 

The official statement was that a component in the formula was no longer able to be sourced.

I noted at the time that over just about a 3 month period, 

- Slot.it N series (22 and 18)
- Sideways Hi-grip in all 3 a-shore values (which were quite similar to N series)
- NSR Ultragrip and Supergrip original formula

All ceased production and availability. It would seem to me there was a common factor in the loss of all these from the market. 

[charlesx]

Thanks Mark. Yes I recall you mentioning some of that before.

You might be interested to know I have turned my small figure 8 test track into an approx. 19 metre track (about the size of Green Acres). Only top clear coat to go then painting slot, copper tape, wiring and borders. Will attach a progress shot taken before I started painting. Used proper router bit this time (not end mill) and your recess tool. All worked great.

Excellent work - nice addition for the club. That looks like it will be a nice flowing circuit to drive

Ta Mark.

Rather off subject but track limited by lean-to function. Am fitting a winch as I am not getting any younger. Roll up still works but at approx. 2.3m wide x 4.8m quite heavy although no problem for 6ft+ tall son.  Like our 6 tracks are all quite different so wanted to maintain that e.g. Green Acres is very flowy and Bowman Raceway very point and shoot (former 1/32nd metal car track. Both of these used only on Sunday. Wednesday tracks include mine; Centennial Park Raceway which is very tight; Skyline Garage Race which is short and twisty but no where as tight as former; The Rock Raceway which is very fast with slightly banked corners. Hopefully mine will be added to Sunday group as some of us race Wednesday and Sunday.

Thanks for your kind comments. Regards Charles Le Breton
