tyre size for cup racer alloys

[Spanky-197]

Hi,

whats the proper tyre size for the clio cup racer alloys?

I don't know what it is, but it isn't a road car size, rather a racing tyre size.

For road tyres you would be fine with 215/45R17's

 

[Spanky-197]

thats what ive got on but they could do with been wider

 

[RalphyBMW]

For looks or handling? Careful with increasing the width as it will make the car more prone to tramlining.

 

[Spanky-197]

thought it would be better to have the proper size tyres for the alloys plus better looks and handling

It's an 8j rim, rather than a 7.5j - so 215 or 225 will be fine.

You can easily fit 235s on an 8j, but going much wider, you'll want to be dropping to a 40 to account for the extra rolling radius, There's also more potential for rub/poke as I think the racer wheels are a different offset too.

My track tyres are 225/45/17 and are fine, cheaper and easier to find too.

+1

I have no issue running 225/45/17

A048 come up nice and cheap on ebay for these.

Mainly from some guy running an elise, one track day then he put them up for sale.

I've been to his house he doesn't have to worry about the cost of tyres LOL

215/45 R17 or 235/45 R17

It doesnt matter which size as one wont give more grip than the other.

235/45 R17 is the closest you'll get to the standard rolling radius with a wider tyre.

I've had both on my 17x8 track wheels and I prefer the characteristics of the 215, a bit more lively

Skinny tyres do maketh more fun!!

oks it will be a while as am going to wait for tyres to wear out before i decide as 2 are new and 2 are 1/2 worn

See here, they're 225 and look to fit well i.e they don't look to be stretched or bulging.

Hope u don't mind me thread jacking to ask a few similar questions rather than starting a new thread :biggrin:

I've got at least 5 track days lined up next year and I'm looking for a set of wheels and tyres to get the best out of the car. Did a few trackdays this summer in the 200 with cup suspension on standard conti tyres and they were good but I know it can be even better.

Been looking at Pro Race 1.2 in black with Toyo 888 which is a pricey option but not sure what is the best offset, widths, sizes etc for max grip and performance.

Ideally I Would like to get some cup racer alloys as i've seen them come up on this forum quite cheap but have missed out and they seem to be really hard to fine.

So what combinations would you guys recommend?

cheers
Ben

Going the cup racer alloy root isn't the cheapest just so you know, though you can end up with something that look's fairly OEM yet is an improvement in looks and performance.

the race alloys do look the best - specially in black
