Please help me with the tire size selection on these rims:

Front Rims 18X9 36offset Tire 245/40 or 255/35?

Rear Rims 18X10 45offset Tire 275/40 or 285/35?

Thanks.

Just to clarify Rominl's suggestion:

245/40 front 275/35 rear

I would not do 275/40 like you were asking. The two wheels will have different size diameters.

@_@ yup, thanks for the correction. i have to pay more attention to the profile...

Didn't want to start a new thread therefore I just posted my question on this one. Since it relates to the same question.

I am getting

19 x 8.5 front
19 x 9.5 rear

bolt pattern is 5 x 114.3

wheel offset
38mm front
35mm rear

Now for the question...
What type of Tire setup would you recommend. Some recommended a "FAT SETUP" but I would like a quite and smooth ride if possible.

NOTE: car will be lowered on L-Tuned springs as well.

thanks

245/35/19 front and 275/30/19 rear would be ideal.

With the fat setup, 245/40/19 front and 275/35/19 rear, there will be a little rubbing of the wheelwell liner on big dips/driveways. You do get a little more rubber which will help with the ride quality.

So you would prefer the 245/35/19 front and 275/30/19 rear.
Any other suggestions will be much appreciated.

Personally, I prefer the fat setup BUT I am willing to put up with the rubbing that will come with that setup. For those who want trouble free (as far as diameter issues are concerned), then the stated size is better.

what kind of trouble am I looking at with the fat setup you prefer??

How bad is ride quality on the regular setup?

thanks

Neo

The ride with the regular setup is not that bad. It will also depend on your suspension. It will definitely not be stock-like. I've also found that a ride that is acceptable to one person can be too soft or too harsh for another. The best way is to see if you can bum a ride from someone with a setup similar to what you are planning.

With the fat setup, there is a bit more rubber. The ride is more like running with 18s. You run into problems because the diameter is now about 1" larger than stock. You can get rim offsets configured to minimize/eliminate fender rubbing. The remaining rubbing issues is with the wheel well liner. With anything that can cause the springs to compress fully (big andfast dips, deep driveways - both public and home), the top of the tire will rub the wheel well.

Again, all this can happen but to what extent, it is hard to say. There are a multiple factors involved (wheel alignment, drop, suspension spec, tire manufacturer) that makes it hard to say anything definitively.

I appreciate the detailed reply, I noticed you mentioned manufacturer for the tire brand. Who would you prefer as far as quiete and soft. How do I go about buying these on tire rack, there are two different sizes for the tires so I was wondering how to actually go about that. Can we buy two and two others or what?

thanks NEO for the help.

What are your thoughts on LOW PROFILE??

Neo

iTrader: (3)

The only tire that I seem to get good general feedback from owners are the Michelin Pilot A/S. They do cost though. The problem with the A/S is that they do not make the 245/285 combo for fat 19s, which is what I'd get with 19s (with appropriate rims specs).

You can buy different fronts and rears from tire rack, even on the website.

Not sure what you mean? Anything on 18s+ on the GS is considered low profile, some more than others. What aspect of "low profile" are you asking about.

nanotech

I am sorry i guess that is what i was saying, Don't know much about low profile .

So you still consider the fat setup?

is there any danger if i am going at high speeds say 90+ and there is like a hilly smooth area. I don't know how to explain it. like on the freeway sometimes. You know?

well i hope i am not making a fool out of my self by asking these questions, I just don't know much about the wheel/tires.

Neo

I guess I have been on 20s for awhile now so I am used to all the issues of having the wheel diameter be an extra 1". I've considered from time to time going to 19s "fat" to get a little more rubber. It would not change any of the issues since 19s "fat" and 20s "normal" have the same diameters.

Since I am used to it, 19s fat does not bother me. For those unfamiliar with it 19s "OEM" might be a better choice.

There are more tires that will accomodate 20s "OEM" spec but that is a whole different thing.
