What size of tires please

**stefos** · 05-12-2010, 12:37 PM

I have a set of 19x9 wheels and I was told that 275/30/19's is the correct size would 275/45/19's be better ?

I dont think a 275/45/19 would fit. I think that would be a WAY tall tire...

you want the 30s

with the 30s you are at 25.5" overall diameter ...that is .16" off of stock overall diameter size...so your speedo will be almost spot on...however 30s are quite thin in the sidewalls compared to the 45s ...30s sidewall will be 3.25" thick compared to the 45s who is 4.87ish" so about 1.5" difference

yup.

just for the op the sidewall height for a stock 17 inch would be 4.33" ish per side.

I thought 275's were for a 10" wide rim.

275/30/19 is the plus 2 tire size for our cars. Your speedo will be within 1% which is totally acceptable.

thankyou everyone for the help , what about a p275/35/19 over a 275/30/19?

Too big at 104% (27.1), needs to be + or- 3% of oem size (25.7). Speedo will be off too much unless you can reprogram ECU. You will loose performance and economy with a larger heavier wheel not to mention putting more stress on the bearings and axels.
