Ok, so I am about to mount and run 19" wheels. 9.5" rear 8" front.

I have 2 rear tires, 275/35 that I boought from stclair who pulled them off the wheels he just bought. He also has the front tires of said wheels that are 245/35. The guy who owned the wheels before him knew his **** and is extremely car oriented.

My question is, can I run these and not have any problems?

the diameters are;
245/35
Overall Diameter: 25.75 in 654.05 mm
275/35
Overall Diameter: 26.57 in 674.87 mm

which gives me about a 3% difference, which will make my car run 3% slower on the speedometer right? So when I'm going 100kms, I'm really be going 96.

Is this really a problem, does anyone drive like this?

Tire Size Comparison

245/35-19 3.4in 12.9in 25.8in 80.9in 783 -2.1%

I know how all the sizing works. I just need to know if anyone is running out of proportion tires problem free.

3% diff inbetween the fronts/back isn't going to be a problem. But you were referring to the speedo so I thought it was the rear dia that you had an issue with

Well yea, I'm not too worried about the speedometer being off by 3 or 4kms. I just want to know if there is any issues I might run into?

I plan to go through the rear tires experimenting with my drop and then replace them with 275/30 instead to even it out.

3% faster isn't it? Same revolutions, more distance covered. Reading 100, doing 103. Except you should be comparing to the stock size, not the front size, so really only 1% as Jeff's post pointed out.

No big deal. Except if you were actually talking about swimwear. Then no.

This is what I run:
This is what you want to run:

Although your sizes have a bigger difference, I'd say you're within acceptable limits. I remember the general limit being 5% or something

^^^+!

you'll be fine. I had 245/35/19 and 275/35/19 when I ran my volks but now im running stocks with 245/40/19(even bigger).

I ran 235/35 front and 245/40 rear for most of last summer, probably an even bigger difference (just over 3%). No problem other than my fronts looked too much like rubber bands, LOL!

I'll be running 245/35 and 255/35 soon (1% difference)

Alright sounds good.

I figured it would be alright since the original owner of Jamal's Volks ran these sizes.

Nghiars; I haven't decided if I'll go with a larger profile tire or smaller next. I usually don't like rubber band tires so I'll probably go up to a 40 SW.

Thanks guys.

Add spacers and stretch that biatch

For sure adding spacers, stretch might come later lol

Wow. Didn't know wider tires would change the diameter. I only throught it was the profile that changed the diameter.

I gotta get tires for my new rims coming (axis pentas). I've got 19x8.5 front and 19x9.5 rear.
What is the proper tire width range for 8.5 and 9.5?

I was thinking of getting 235-35 front and 265-35 rear. How's this setup?

Also why do people get higher profile up front or rear?

What tire size do u guys recommend? I've got awd.
Thanks

Well the sidewall number is just a ratio to tread width right?

So running a wider tire will change the spedo if you run the same sidewall number on the wider tire.
