Other Tire Sizes for GP Wheels
 

There aren't many Tires available in the 205/40-18 Tire Size. Actually, according to TireRack.com, there are only 4 different tires available.

I want to ditch the Run Flats and go Non-Run Flats.

What other tire sizes would work with the GP Wheels??

According to TireRack.com, another option I have is 215/35-18 but is there any other sizes?

Also....
I recently ordered 16x7 O.Z. Superturismo WRC Wheels with All-Season Tires (195/55-16) for the GP. My plan is to use these (O.Z. Wheels) for daily commuting and use the GP Wheels for Track/Auto-X Events. The GP Wheels will have Ultra-Peformance or Higher Summer Tires on them.

Any help would be appreciated.

Thanks.

I run 18x7 R109 factory wheels with 225/40/18's. Now that's with a 2" drop so at stock height there shouldn't be any rubbing issues at all.

Not sure it would work on the GP, at least no one on NAM has reported that size on a R53. And I have searched MINI2, Motoring Alliance, GPnet, Motoring Underground, Total MINI, MINI Torque. The good news is that no one has tried it to confirm it does not fit for sure. But 225/40-18 offers the best tires. I hope someone tries this size on the R53. There is a post by MarioKart that says he purchased 225/40-18, but his sig reads 225/35-18 (which is what I got-you will need a 5mm spacer) midMOmini Sig says he has 225/40-18 RT615s but his Gallery and Sig got All-Seasons?

I use 215/40-18 on my GP.

Any updates on 225/40-18 fitment on stock GP?
Sorry, to revive old Walking Dead Thread.

I threw on some 205/40/18 on the stock GP wheels. I'm looking to throw on some summer tires on my 18x7 OZ Superleggera's but have no idea what to go with. Any one have any ideas?

The summer tire choices are a little limited for 18x7 wheels. 215 is about the widest width recommended for the 7" wheel. I use 215/40-18.
I use the Michelin Pilot Super Sport with a UTQG of 300 because they were the stickiest option a few months ago when I purchased tires. I like the Michelins.
However, I see that Bridgestone just came out with the Potenza RE-71R in 215/40-18 with a UTQG of 200. I would really check these out. They would have been my choice if available three months ago.

Thanks for the feedback. I am going to try to go with the 205 Michelin PSS as I will be doing some street/road driving with these tires/wheels. I heard the Potenza's are great tires but more strictly for track use as they have a much faster wear due to their stickiness
