What is the biggest tire that can be put on 19X8.5 w/ 37 offset and 19X10 w/45 offset. This would be for a 430 with L-tuned drop and I don't want to modify the fenders. I would like to try and fill the wheel wells.

245 and 275 are the typical choice, i would recommend those

245/35 and 275/30 if you want to be within spec

245/40 and 275/35 if you want to have fat tire setup for better comfort but out of spec

I imagine that the fat tire set up being out of spec is pretty minimal. Would it help fill the wheel wells? Will it rub? Could I go a little bit wider at all? I kind of prefer the tires being a bit wider than the rims. I really hate the stretched tire look. I don't know that much about tires but could I go with something like 255/35 front and 285/30. That may be a silly question but hey I won't know if I don't ask I see some peoples set up and they look great because they either flush up or go slightly past the edge of the rims. Maybe it's the brand of tire they are using Thanks for the help.

I don't like that stretched look either. 245 on 8.5" wheel and 275 on 9.5" wheel will make for a pretty straight sidewall with most every make of tire (IMO, 285 is too wide for a 9.5" wheel). The 245 will be slightly more 'stretched' looking on an 8.5" wheel than will the 275 on a 9.5", but not bad by any means). Those are the tire and wheel sizes I have on my car.

it depends on what brand and model.... for example, i have 255 and 285 on 9 and 10.5 on my sc430. they both look scretched.

but on my gs400, i have 245 and 285 on 8.5 and 10.5, you can't see stretching on the rear tire

so did the 275 on my previous 10" wheel in the back, no stretching.

get meaty tires and 245/285 fits fine on the wheels. if you get meaty 255 and 285 and put them on 9 and 10, it will actually kinda "bold" out a bit

with fat setup, you will rub the top of the front wheel well on big dips

It is about an extra inch in diameter. You will rub the top of the wheel well liner if you are going fast enough and hit a dip big enough. It will fill the wheel well better.

Well, with any of the recommended sizes, your tire will not have the "stretched" look associated with the VIP cars. If you run 255/35, you run a little more risk of rubbing the sides, especially on places like steep driveways. 285 is a little wide for 9.5 rims. You can mount them but I would not risk it.

Unless you modify the fenders (or neg camber), you will not be able to do this.

What do you think about 285's on 10" wide wheels? Any problems?

With your offset of +45, you should be OK. It is right on the borderline though.

umm, i am not sure if it's ok. i know 43 or 42 is max for 10 with most 275 tires. 285 is a good 10mm more, that's pretty wide. you might need to shave a bit

On second thought, I think Henry is right. I was comparing what I was planning next but then it has been so long that I kind of forgot that I have it shaved a bit. It would have worked for me but not a stock fender.

As Rominl indicated, you'll need the offset exactly right to get them under the fenders without any work on the lips. And that's assuming that you are running stock or near-stock diameter tires. If you go with the 1" taller-than-stocksetup you'll have to rework the plastic ground effect thingy at the lower front of the rear wheel well opening. It's not a big deal to do, but you'll have to remove the screws, bend the mount in a little bit, and then reattach the plastic piece using a different type of bolt in place of the upper screw (it'll be obvious what you need to do once you get started). If you don't, the outer shoulder of the tire will rub on the head of the screw when the car goes over dips and the suspension compresses.

If your question had to do with 285-mm tires fitting 10" wheels, then the answer is that high performance tires such as Pilot Sports, Potenza S-03s and such will not look stretched at all in those measurements. In fact, 285 is about the widest tire that should be on a 10" wheel, from a performance standpoint.

I had the fat tire setup for over a year. I was droppped 1.9/1.7 and I didn't rub. You should have no problem on Ltuned drop. Check out this thread for pics and specs of my wheels. VERY close to what you want.

umm, shouldn't have to do that if you get the right offset.

when i had my old hre 10" back with 275/30/20, it was 1" out of spec overall diameter, but i didn't have to do any mods to my rear fenders at all

but now with my 10.5" with super aggressive offset and 285/30/20, i do have to shave the whole fender and more to get it fit well

TexasGS

Thanks to you all for the great input. I decided to just go with the standard 245/35/19 front and 275/30/19 rear to stay in spec. Going with the Toyo T1R's.

Perhaps the Dunlops are taller than they calculate to be. They rub on the TREAD area, so offset doesn't really figure into it, unless you had an offset that positioned the tire about 1" further inboard, and that would look pretty bad.
