I've got a 2004 G35 Coupe, stock suspension currently with OEM 17" (soon to be up for sale ).

I've decided on a new set of Enkei RPF1 18x9.5 +15 up front and 18x10.5 +15 rear....looking at the ContiExtremeContactDWS tires.

Im looking for a size that wont rub or need fender rolling, car is not going to be lowered...does anyone have any experience or opinions on the following sizes??

245 -40 -18 diameter= 25.7"
275- 35 -18 diameter= 25.6"

255- 40 -18 diameter= 26" - Tire Rack recommendation
275 -40 -18 diameter= 26.7"

265 -35 -18 diameter= 25.3" - Wheel Shop recommendation..small rub chance
285 -35 -18 diameter= 25.9"

Thanks for any help or advice...I'm new to the G and appreciate learning from you guys.

 

245/40-18 front 275/40-18 rear is what I would do. Correct tire diameters and has a great selection of tires with that combo. Ran those sizes on my 6MT on Eibach's and had no rub.

 

Hi Neal....I didnt know you were a mod here....I remember you from another forum I used to use....Thanks for your advice! The other rep I spoke with thought the closer diameter would be better for the electronic stuff, but I'll take your first hand experience any day. Ill give you a call next week to order.How do you like the Conti's? I need an all season....I've read really good things about them.

 

Sounds good! Conti has been quite popular since it launched. Better than the previous version but I don't think it will live up to the hype long term.

 

I'm onlyl really questioning the tire choice, why do you want all-seasons on such an aggressive wheel combo? Maybe consider the slightly sportier Continental DW? Also the first two tire setups you posted will be stretched.

I would personally go for the 265/285 combo, but thats just me being me!
