Slicks - Sizes

[172bagss2]

Can anyone please confirm if the following size of slicks (Dunlop SP Sports) will fit on 7x15 wheels:

210/580R15

Cheers, Paul.

best bet is the 185/555R15 or 175 version with the same side wall height, they work out as - 185 = 204mm width (205 normal tyres) and 175 = 191mm width (195 normal tyres) ish

it says 7J is optimum for the 175 and 7.5J is optimum for the 185's but 7J is in the middle of the permitted width for both.

Not sure on the price of the 175's anyone know?

You could also look at the michelin ones that 182 race car used?

Thanks Dave, to be honest I'm not shopping around.

I wanted to try some out on a track day or two and I've been offered a set of the above size for a cheap price but just want to make sure they will fit!!

From what you're saying it sounds like they might be too wide??

 

[d4ve86]

they dont have the 210 listed in 15" where im looking but they do in a 16" and its 223mm width - 8J optimum and 6.5 - 8.5J permitted, should be ok but there going to be wide like 225 width tyres might be ok in the arches im not sure.

Thanks guys for your help, especially Dave (not so much Ben)... :rasp:

I've looked on Dunlop's website and the size that Clio Cups run is 185/580R15.

Like you said Dave said, the 210 width doesn't seem to be right for a 15" tyre - so I've gone back to the dude with them and asked him to check that they are 15s (not 16s) and that the 210/580 bit is correct.

I also spoke to Speedline and double-checked what I have. The wheels are 7x15 aluminium 2118s, about 3 yrs old (courtesy of LeeP86 ). After a bit of a scrub they should look great - esp if we can get this rubber to fit them!!

just be carefull u dont start damaging ur output shafts. the grip will be great thought. u can also cut the slicks to make them into intermedits. due to the english weather!! enjoy ur track days. ps some circuits wont let u run slicks unless you have a roll cage fitted. hope this info helps!

Good job I'm picking them up on the way HOME from Croft anyway....

Thanks mate, sorry if it's a daft question but why would fitting slicks risk damaging d/shafts? :S

the amount of grip puts strian on on D/S, bushes, bearings etc.
