Tire size help

[9mmJ]

I don't know squat about tire size. Are all 16" rims a standard width?

I picked up a used Silverado with 275/65 r16 off road tires with some aftermarket American Racing 16" wheels. The tires are loud and drive like shit.


Can I put stock 255/70 r16 on these wheels? Tire Rack has some for $94 that should really improve the ride.




Thanks!

I dont think there's a "standard" width. Is there any marking on the rim that indicates its width?

[DYoung]

No, not all 16" wheels have the same width. Usually 275 width tires are mounted on 8.5", or 9", or greater width wheels. Tirerack has good customer service techs who may be able to answer your question.

The 255/70 tires may be too narrow for the American Racing wheels.

Contact AR and see what they recommend. Never go smaller.

According to BFGoodrich, the acceptable rim width for a 255/70/16 is 6.5 to 8 inches. The acceptable range for a 275/65 is 7.5-9.5, so if your wheels are 16x8 (fairly common), you're golden.


ETA: I used to do this for a living years ago. Rim width is measured inside the beads, so outside dimension on the wheel including the lips will normally be about an inch greater than the actual rim width.

Well crap, I'll try to figure out how to measure these rims.


Thanks so much for the info.

The 255/70 tires are going to be only .25 mm shorter and 75 mm narrower than the 275/65 tires.

The first number is tread width, and the second number is the percentage of height of sidewall to width.

Arent they going to be 20mm narrower?

According to my Grandson's math teacher, "There is no wrong answer, everybody is Right."

So, with this form of math, we are both right.........[Tooth]

Tons of tire calculators out there... for this situation, this one works fine: http://tireconvert.com/

Take off the wheel and look on the back of it. Manufacturer stamps wheel size and width on back.

[9mmJ]

Thanks, I'll try that this afternoon

same height and .8 inch narrower then what you have now. Unless you have really wide wheels it should be fine.

If you are buying new tires get somthing good like duratracs or bfg at, they will last a really long time and work well.

Cheap tires wont.

Are the tires cupped?
