Hello, I have several questions and I am stuck in a big problem. I just bought new tires for my 7th Gen Accord Coupe v6. The old tires I had on my 18" rims were 235/35/18 (Hated the low profiles). I decided to up the size and buy new Nexens at 245/45/18. I do plan on lowering my car this spring. But, my problem is I just got the new tires on yesterday, and the rears rub on my wheel wells when I hit a bump. I have researched and found people that have dropped the same car some with the same 245/45 tire size and not had any rubbing. What I am confused on, is I dont know what the issue could be of why they are rubbing.

Should I drop down to a 240/45/18?

Does my current Aftermarket rims not match the correct offset to lower? (40.00mm offset)

Do I just keep the tires and get my fenders rolled?

Please help, like I said. I'd like to lower my car this season. But, I dont want to spend a lot of money only to have my tires rub. Anyone have a complete set up of their specs that has lowered their car? ex: Offset, rim model, tire specs, coilver brand, etc. Please help! Thanks !

I just moved this to this correct forum where you are now reading this..

Welcome

 

Several comments:

• Both tire sized you mentioned are incorrect for your car and will induce speedometer and odometer error.
• The stock wheel size for your car was 16" and the stock tire was 205/60 R16 which equates to an overall wheel/tire diameter of 25.7".
• The 235/35 R18 tires were too short in that their diameter was 24.5", and that in turn means that your wheel gap was over a half of an inch wider than stock and your speedometer registered higher than your actual speed and your odometer logged more miles than you actually drove.
• The 245/45 R18 tires go too far in the other direction in that they are too tall; your fender gap is now almost exactly a half of an inch less than stock and your tires are well over an inch wider than stock, hence the rubbing. That and your speedometer is now registering a slower speed than you're driving and your odometer is registering fewer miles than driven.
• My recommendation would be to drop to down to a 17" wheel and mount a set of 225/50 R17s on them. Doing this will correct your instrumentation, give you a taller sidewall for pot hole tolerance and such, provide good handling, and give you some room to drop the car a bit.
• If you're wedded to the 18" wheels, then you might want to consider a set of 225/45 R18s; they too will put your instrumentation back in order, however, because the wheels are probably pretty wide, you may still encounter some rubbing if you drop the car.
