Tire size -street to racing slick

[k98dave]

Looking to get some take off slicks for track day use, Track Wheels are 18X9 Ft and 18X10 rear with street tires 255. F and 295 R , What would be the sizes of full slicks?

Dave,

Go to usedracingtires.com and you will find a very beneficial subgrouping for specifications on tire sizes. Most used racing tire distributors don't list this info and it is highly valuable for info on rim size and more. Check under Pirelli and Michelin primarily, and it appears you would want something from a 235/645/18 up to a 285/645/18. There is also a listing for a 265/660/18 and no diameter is listed , but it might be a better height.

To be frank, your best option, long term, is to get a set of square rims so you could rotate the tires all around for longer life. I am pretty biased towards 18x11s, even though that means getting 25mm spacers for the front. Also you need to get extra long ARP studs for the hubs, but this is really something I suggest everyone should consider not just for fitment , but for safety. Good luck and I hope this is helpful?

Yes thanks, From what I could see they have the sizes I would want but for now only single tires. I will check back with them

Things loosen up after Daytona, but later this year when they have run some of the flat tracks , the choices are better and not designed for the banking.

It's going to be a little difficult to find slicks for that narrow of a wheel up front, that are also the right height. Out of curiosity, since this will be a track only setup, why not run 18x10 all around or 18x11? It'll provide much better handling and performance, while also making tire selection easier.

Haven't found 2 more matching 18x10 wheels. Been running these wheel sizes with 200 rated tires so just wanted something a little sticker
