Alternative tire sizes

[rwh963]

i will eventually be replacing my stock tires (265/65/17). wondering what alternatives others have had success with using. thinking of 265/79/17 right now.

There is 265-70R17 (31.6") which is the common 5th gen size . There is 255-75R17 (32.1") which is a Jeep wrangler size. 275-70R17 (32.2") not a common size but has a few options. 285-70R17 (32.7") seems to be fairly common. Those are all the sizes I know off the top of my head.

i never understood how the 285 70 or 275 70 are taller than a 255 75, all on the 17" wheel...

I think the 70 and 75 number is a ratio, thus, wider (275 or 285) even though not as great a height/width ratio ends up taller overall.

stock suspension. partly asking because pricing can be noticeably different for near sizes. also, a previous vehicle, a honda crv, had a stock size of 205/70/15, and i upgraded to a 205/75/15 and it made a noticeable visual difference (in a good way).

You can use 265-70R17 with stock suspension. They fit but there may be a little rubbing. I had some Grantrek takeoffs on my with the stock suspension for a while before I lifted mine. 265-70R17 is more common and has more options and most versions of a tire tend to be a little cheaper in this size.

like [MENTION=225632]woodman60[/MENTION] said. it is due to the width of the tire. Height of tire=(2*(aspect Ratio*Section Width)*(1in/25.4mm))+Rim size. For 265-70R17:

31.6"=(2*(0.70*265)/25.4)+17"

I use this because it is far simpler:

the second number is the sidewall height in millimeters. It is the percentage of the width called aspect ratio

So 285*.70=199.5mm

199.5*2 because there's sidewall above and below the rim

399mm/25.4=15.7"

15.7" of sidewall plus 17" rim = 32.7" overall diameter

the 255/75 has 15" of side wall and overall diameter of 32"

every tire is a little bit different in size but that's how it works

I switched to Discoverer A/T3 - 265/70R17 and I had to make some mods to the fenders upfront to reduce rubbing. This is on an 07 Sport w stock Xreas. Otherwise they handle great.

265/70

When I bought my Runner (from 2nd owner) he had already installed 265/70/17s and they worked fine. It was stock, no lift, no spacers, stock rims.

I only had an issue with rubbing after I installed 1.25 inch spacers. Even then I only had to move the finder liner forward some, maybe a little rub on the mud flaps at full turn.

It also depends on what type of tires you get. The thread pattern has a lot to do with rubbing as well. If you're going highway tire, not too much to worry about on rubbing but if you're getting an AT that has more aggressive patterns, you're going to rub. I had new Ironman ATs installed from the dealership when I purchased my 08 and they rubbed so bad. Had to do a 1.5in leveling spacer up front and still cut a tiny piece off of the body to get them to completely stop rubbing. With stock suspension, and all terrain tires at 265/70/17, it's going to rub if you do no modifications to the fender liner or anything.

Go 265/70/17 because it is cheap and very common, also gives you some extra ground clearance as well as it is wide enough as well so it doesn't look like pizza cutters.

If you have a lift or plan to lift, go 285/70/17 because it will never be wide enough lol. You will always want wider and bigger.

this is my hope/feeling. probably going from general grabber hts 265/65/17 to grabber hts 60 265/70/17. like to get a slightly more filled in look in the wheel well. have absolutely no inclination to do suspension mods.

I failed to mention that I have 1.25" spacers as well. There is no rubbing with the spacers on and the stock tires.
