Tires on my Exp. with 67m miles are due for replacing. The 00 2wd, 5.4L Eddie Bauer came with 275/60/17 tires mounted on 17x7.5 rims. While I don't do much off highway I do need more clearance than this truck currently has. Will the 275/70 or 275 or 285/75 tires fit properly on these rims? I don't do any towing with the truck so loss of torque will not be an issue since the 5.4 seems to have plenty of pep, but realize that my speedo will be off quite a bit if I should go to 275 or 285/75 tires.
Thanks,
Walt

 

ok lemme try to put this so that i understand it also..lol j/k....i have the 17 x 7.5 wheels also......with 265/75 x 17 tires.....basically the 265 number is the height of the tire.....so cross reference it equals 31......now the 75 is the width of the tire.....which is 10.50 inches......and the 17 is self explanitory.....so in reality the 265/75 x 17 is a 31/10.50 17 tire.a 285 tire equals out to be a 32.so yes u can put a 285/75 17 on these wheels......along with the 275"s

 

Incorrect. 265 is the width in mm (265mm=10.4"). 75 (aka the "series") is the ratio (in percent) of the width of the tire to the sidewall height. So a 265/75 tire would have a sidewall height of 75% of 265mm, or 199mm (7.8 inches). The last number is the rim diameter.

So, in this example, a 265/75-17 tire would be a ((17 inch*25.4mm/inch)+(2*199mm))= 32.7" diameter tire, which is 10.4" wide, mounted on a 17" rim.

This all assumes the tire is mounted on a rim which is near the center of the manufacturer's recommended width range for that tire. Higher profile tires (eg 75 series) are more tolerant of rim width than lower profile tires (eg 45 series). Typically, for each +/- 0.5" in rim width the tire's sectional width changes +/- 0.2". Check with the manufacturer's or Tire Rack web sites for rim width specs for each tire.

 

I'll check the tire rack website. I want to get a tire that will fit within the mfg. guidelines for rim width so wear will be normal, plus want to have the tire fit within the wheel wells without modifications.

 

I have 265's and they are roughly 31 1/2"'s tall.

 

Lmao i knew i should not have tryed to answer that.....i confused myself.........ahh well live and learn......i know what fits on the wheel ........lmao thats what i get..thanx for clearing that up........lmao

 

Trying to figure out tire sizes can be frustrating.

I found a site that allows you to compare tire sizes. It will show you an over lap of the sidewall or tread. It will also show you the rim size in relation to the sidewall. Very cool.

It will even tell you how much your speedo will be off as you deviate from the first tire size you type in.

this sounds strange but the site is

enjoy.

 

I have a pair of 285/70/17" tires on my truck they speck out at 33" tall and 11-1/2" wide the stock 265/70/17's I belive were about 31.6" tall here are a couple pics. top pick is old tires bottom is new.

 

I have a set of Pro Comp 33x12.50x17 on my super crew. The tires only have 300 miles on them. I am looking to sell them if anyone is interested. They fit just fine on my truck. It's 4x4.

Why are you getting rid of them so soon? I've heard they were pretty good tires.

How much are you asking for them?

I just bought the truck and I am thinking about getting MTR's

I think they are supposed to have a 50,000 mile warranty but I am not sure.

Creole...I will email you a price...
