A lot of Guys drop down to 40s on the front and 35s on the rear on stock wheels. Has anyone gone the other way with 50s on the front and 45s on the rear? I'm looking to gain just a little more underneath clearance.

Thanks

You have to be very careful of the size ratio between the front and rear tires. If you get it wrong,,,, You will have ALL SORTS of EBTCM handling issues and messages.

Why don't you just use the spring adjusters and raise the car some over the OEM adjustment??

You have adjustment for FRONT and REAR.

Thanks Bill for the reply. I will make those adjustments. It may be enough to get me where I need to be. My driveway gets me 75% of the time so I don't think it would take much.

from a previous post. I am very happy with the narrower/taller tire - ride especially.
=============
What you will run into is that while there are plenty of taller tires, they will NOT work on the stock-width wheels (tires too narrow in bead section). Check under the tire specs for the "recommended wheel width". Installers like Discount Tire etc will absolutely balk at installing tires that are not spec'ed for the existing rim size.

The best I could find were Bridgestone Potenza S-04 Pole Position, 235/50R17 (front) and 255/45R18 (rear). They are rated 280 AAA, and are 26.3 and 27.0 inches tall, respectively, compared to 25.6 and 26.7 for stock Goodyears. Mine is 2003 50th convert. I ended up with a very modest increase in height, but they fill the wheel wells better, I don't scrape on every bump or dip, and the ride is 50% better than the stock-size run flats that were on there (Michelin Pilot Sports).

You might also try the BFG g-Force Sport COMP-2 in 255/45-17 and 255/45-18, which are 26.1 and 27.1, respectively. They are being phased out I think, and harder to find, however.

You can research for yourself, but these were the only ones on the market that were taller, fit the rim widths, featured decent performance, and offered a front/rear set. Many brands and models have fronts or rears that seem better, but then you find there is no matching front (or rear) to make a set.

I am very satisfied, especially with the ride improvement, and, although slightly narrower in tread, the performance is at least as good as the Michelins and to my mind, better. Get these from Discount Tire when they run a $100-off deal, and lately there is also a $60 Bridgestone rebate. They will make sure your TPMS is correctly calibrated, but you will have to pay someone $100 or so to re-calibrate the speedo for the taller tires. It's worth it because when they re-calibrate the speedo you also get the rest of the standard re-flash goodies (like lower fan turn-on temps, no more skip-shift, etc etc).

I have '97 stock 17 /18 wheels/tires and am thinking about going to 18/19 and larger tires. What issues could I create? Considering the difficulty of finding a replacement EBCM, should I take the risk?
