Not feeling the stock tires that came on my 2009 sc..anyone know if 235/60 or 235/65 will work without rubbing?

235/55/18 max!! 60 or 65 is way too tall. A lot of your hate towards the tire on your sc is because of the crappy goodyears. Upgrade to some general uhp's in a 235/55 or a better all season. It is the stiff sidewall and crappy compounds they use in the stock tires. My 20" General UHP's with a lot smaller sidewall ride better than the stock 18's. Get better, not bigger.

would a 225/60 work? I am looking to also fill out the wheel wells without lowering the car..Thanks in advance

I run 225-60-18 on a stock height EX

Will they fit on an SC is the big question. Don't forget the SC approx and inch lower than the EX.

To original poster: fill out your profile. If your sc or even any E with an auto transmission, going more than 3% in diameter really screws the way the trans is controlled by the computer. It may take time, since your E is new, but it does harm the trans unless you can figure out a way to have the computer reprogrammed for the new tire height. Also, you DO want to call your Honda dealer, ask them if you change the tire to a taller tire, if it voids the warranty, all three of my nearest Honda dealers said yes, it voids the trans, axles, and other associated parts. If it is a manual, it does not matter, you control the shifting. Now, 235/55 is a great size, I ran them on mine, looked alot better due to the broad shoulder design of the tire. Now with the 235/55, I was close on rubbing the strut, a 235/60 would probably hit.

235/60/18 Tires

OK, 8 years later, anybody else wish to opine on insane_sc's comments that larger tires will screw with the auto transmission's computer? As a natural skeptic, somehow I'm not buying it, but I'm OK with being proven wrong!

Anybody else fit 235/60/18 on an SC?

Larger diameter tires will cover more ground with less revolutions, so it will definitely throw off your speed reading, which would require a reprogram of the ECU but isn't necessary. The added weight incurred by a heavier tire may affect spinning inertia weight on the engines ability to speed up or slow down the wheels, but not to any significant amount that may damage components unless you significant increase wheel & tire overall weight. This is all as far as I know.

Thanks E.Honda, makes sense.

If my calculations are correct, 235/60/18 is 4.9% larger than 225/55/18, so indicated 60 = 63 mph, 70 = 73, 80 =84, etc. No biggie!

I've been putting larger tires on my vehicles since 1966 when I put 165/80/15 on my '63 Beetle with standard 155/80/15. Zero issues to date!

Ha, I was (or maybe I still am?) a VW guy as well. I’ve also stuffed larger tires on everything I’ve ever owned, including bicycles.

Running 235 /55 /18 Nokian Entyre 2.0 on 18x8 +45 offset mag wheels doesn't rub but i would not go wider or taller than this on a stock EX!

I am also an old VW guy having owned several aircooled VWs. Is your GTV username in remembrance of the Joe Vittone Econo Motors EMPI GTV Beetle.
