I asked this question on someone's thread a long time ago but didn't get much of an answer.
I was planning on going with the 245/40ZR17 Bridgestone Potenza RE-01R on my stock 04 BBS rims (7.5 inch). I am on JDM pinks as well as the RCE lowering camber plates. The specs say that you should have an 8 inch rim but I've read of some people running this size on 7.5 in rims.
Has anyone with 7.5 in rims used this size tire on a ride height similar to mine? Any regrets?

Dont know if this answers your question but I ran 245/45/17's on my 04 BBS's. Stock ride height but it really wasnt even close to having clearance issues with height...the problem is clearance of the rear struts...which I did not have a problem with for the 2 years that I ran on them.

i had these on an 8" with no issues, i would doubt you would have issues on a 7.5"

edit: im on rce springs as well

Thanks, but I heard the 05's have more clearance than the 04's. I think it has something to do with that small "fender" type thing in the rears that the 04's don't have.

05+ have factory rolled fenders i believe

i'm tempted to run a 245 tire with the exact same setup as you...with no answers!

I ran an even bigger 245/45/17 Azenis RT615 on my 04 BBS with RCE Yellows last summer. I had slight rubbing up front only very occasionally (slow u-turns), but they were fine and I didn't feel the need to roll.

How did you like that set up? Was the increase in grip substantial?

[yakmasterjack]

I really like RT615s. I felt an increase in grip from the 245, but I'm running 225s again now and those haven't felt considerably different on the track. Because my car isn't a complete track whore yet I didn't feel like I was totally using the 245s, but it looks like your car is setup to take advantage of that extra width...

245s definitely fit though

I will most likely go with the 245/40 as opposed to the 245/45 to save on weight and hopefully have better steering response since there should be less sidewall flex. Is my logic flawed?

[ScubaSmith7599]

Not flawed as far as I know.....but I wouldn't really consider response/turn-in with your setup. You're already destroying it with going so wide a tire on such a narrow wheel. More grip, but your response is going to suck.

Maybe you'll notice it, maybe you won't. Depends on how hard you drive the car.

I drive the car pretty hard. I track it about once a month. When I went from the stockers to Advan A046's (235/45) I didn't notice a decrease in steering response.

here is my car with Kumho 245/40/17:







I do get slight rubbing on the inside of the fender well when the car is that low, but for track i raise the height about a inch and the problem goes away. i am on coilovers BTW. the tires stick out a little further than the rim, but not by much. point is they do fit.

Thanks for the pics! Are your fenders rolled?

[norcalbugeye]

no problem.

and no rolled fenders. suprisingly it is deep inside the fender well where i get the rubbing issues.

Did you notice a large decrease in steering response?
