Tried Camskill etc., but they only do track tyres. I want full racing slicks though.

For drag racing - try Hosiers

The only one I can see that you have a chance with keeping the standard rim is "ET Street Radial" "3793R" they are 255/50/16. I’m not sure how you would get them to clear but I reckon you might be able to.

Yeah, I was just looking through the catalogue. I don't think they would fit.

I want them for track days and drag racing so I don't want to try to squuze an oversized tyre on the rim...

Looks like Nobbys link to Hoosier do them off the shelf 46610 225/50/16.

Kumho Motorsport Tyres in the Uk sell them

You won't be able to use Hoosiers or any drag tyre for track or road use, the sidewall is way too soft. A full on slick is often not allowed at some track day venues either so if you want a "jack of all trades" then look for a semi-slick or cut-slick tyres.

Micky Thompson make road legal drag spec tyres,they have cuts in them and are E marked too.

I'm not after drag tyres as I said. So, I want something with a strong side wall. I was thinking about 888's or something similar, but thought I would compare them with full slicks if I could find them.

Since I would be fitting them on a spare set of wheels, I would not need road legal tyres.

They are still absolutely zero use on track though.

The obvious choices are 888s, DZ02Gs etc. If you are not worried about driving on the road then a full on slick, just make sure you can use them at the track of choice. Alternatively, take them to a tyre place where they cut them with a basic tread pattern.

You are forgetting the Kumho V70 trackday/road legal tyre.

Kumho V70 is a much better tyre than the 888,s.
The V70 is E marked and therefore road legal.

I watched 2 race cars try both types of tyres for a few hours round a race track a few weeks back and the Kumhos were better in the corners by a mile according to both drivers.Also the lap times were 0.3 of a second faster aswell for both car.

Kumho full slick race tyres

flea what tyres where you using on your best 1/4 mile pass? sorry for sorta stealing the thread

I beg to differ. I've used both and the Toyo R888 holds up much better for a heavy strong car like the 20VT. The Kumho's just deteriated, big chunks flew off no matter which pressure I used. Grip worse too. That said, it was the mid-hard compound so the "hard compound" maybe is better. But I still think it's for tinier cars.
