Default What sizes for new wheels

I just bought some MRR m755 wheels (18x9.5 and 19x11) for my car. From all of my research I have found the tire sizes for the wheels if I were to run summer tires like 305/30r19 and 265/35r18. I have thought about looking into all season tires (maybe brand too) and wonder which tire sizes would be best?

275/35 and 305/30 would be my choices there. A lot of tires come in both of those sizes so you can easily find two pairs.

You're right there is more. Too bad I can't find really any all seasons in 305 just only summer tires.

One man's opinion here but....

All seasons are no seasons.

They do three things, marginally at best. You'd be better off getting a summer tire for the nice wheels and a winter tire for the others, if you think you'll drive in cold temperatures often. Plus, it will keep your nice wheels nicer for longer.

I went with wheels from tire rack. Flow one race spec

I'm running 275/35R18's on the front and 305/35R19's on the back. Love the way they look and drive. Be prepared to adjust your speedometer though, I did because I hate guessing.

Those sizes would be a good choice.

I looked at all the tires and some and I'm guessing I'll have to get the speedometer adjusted.

Bridgestone Potenza S-04 Pole Position: 275/35 and 305/30
Nitto 555 G2: 275/35 and 305/35
Continental Extreme Contact Sport: 275/35 and 305/30

Is the 305/35 and 305/30 going to make a difference with the TCS?

I wouldn't run a 305/35. That's over an inch taller than a 305/30.

You'll barely need to worry about the speedometer.

275/40R18 to 305/30R19 is a 2% difference. At an indicated 70mph, you're traveling 68.7mph. Nothing to lose sleep over. Unless you already have HPTuners and can do it yourself, I wouldn't pay money for that minuscule difference.

Punk...I went with the Pole Position tire over the continental. Most of the reviews say the sidewall is better in the pole position tire over the continental. Everyday driving you probably won’t notice a difference. I can’t comment on it yet, only have about 200 miles on the setup. Currently have 4-5 foot piles of snow at the end of the driveway, not going to test it out anytime soon.

Lots of people run a 265/35/18 and many run a 275/35/18, also. The 265/35/18 is right at 1" shorter than the 305/30/19 rear which keeps the sidewall heights close to the same. Some people like Sean and Wayne are running a 275/35/18 front and 305/35/19 rear. About the only downsides to a 305/35 is less tire selection/higher cost but if you need the taller sidewall & height, nothing wrong with that combo, either.

I went with a 265/35/18 front and 305/30/19 combo on my car, before I went widebody.

I decided on S04 Pole Position tires 275/35 and 305/30. I do wanna go widebody in the future. Probably need spacers eh?

You'll need spacers to fit the wheels flush with the widebody, but that's okay. Lots of guys do that (or get wide body fitment rears).

Good choice on those tires.

265/40R18 and 305/35R19 will have the same size sidewall if that matters to you, and will retain a roughly 1-inch diameter difference to keep the computer happy.

Computer doesn't care, as long as the front tires aren't taller than the rears.
