Default Aftermarket wheel setup question...

Why do most wheel setup here in CL carry 265/30/19 in the rear instead of the recomended 265/35/19 by most tire dealers?

265/30/19 actually decreases the standard diameter by 3/4 of an inch.

Please help. I am in the market for new shoes. Bought S5:F 19's 8.5(+30) and 9.5(+35).

it all depends on what type of drop and look and flushness you are going for.

If you are planning to put coils, slamming them and want a flush look, you will have to stretch the tires. A lot of people will run 235/30/19 on a 10 or 10.5 wide wheel so they dont rub.

If you are going to use stock suspension or just do a spring drop you can run 265/35/19 or even 275 and will have no rubbing issues and probably a smoother ride.

So basically smaller and skinner tires are used as you drop your car lower and push your wheels out to a more flush stance.

^agreed.

I'm on 8.5 & 9.5 wheels like you. I've found a good balance between a modest stretch and also having actual tire on my wheel to have decent ride quality.

Go with 225/35/19 fronts & 245/35/19 rears... best balance I've found.

With this I've managed to pull of +22 offsets all around with no rubbing (after front & rear fender mods of course). I'm also semi/slammed on coilovers.

But if your just on something like Eibach springs with no plans on rubbing, you can go bigger... like 235/35/19 fronts & 255/35/19 rears.

FYI - Just IMO, I would stay away from the 265/30/19 or 275/30/19 stuff... keep it a 35 in the rear as well.

Also, there is a greater number of manufacturers that make tires in the 265/30/19, 275/30/19 sizes. Why not try 255/35/19?

I'm running Toyo T1R's 275/30/19 on 19x9.5 45 rear wheel. Looks great, fills rear wheel wells nicely, handles very well, stops very well, no rubbing.

I originally ran 275/35/19s tires in the rear with 19x9.5. The problem is that when I dropped on coils, I started to rub. Switching to 265/30 solved that. Plus, the lower sidewall looks better than a fat tire (subjective).

I chose 265-35-19 in the rear because I'm not dropped. I hate the gap, but when I get coils I'll switch to 30 series.

Not to hi-jack the thread, but I also have a tire question on 19" so instead of creating another one, I'll post here....
I have 19x9.5 +35 R planning to run 255/35, lower on coilover (not slamming, but little to no gap). Think it will rub. Feedbacks are appreciated

What tire brand and type? (because that has a bigger impact on the ride than small difference of 30 vs. 35 series profile)
