Widest tires on stock rims '06 2wd

[stoop]

Hello Gents, I have searched everywhere but I can not seam to find any posts about running wide tires on a completely stock setup. Can anyone tell me the widest tire they have mounted. I am thinking of putting 255/60 15's on the front and 275/60 15's on the rear stock rims and ride height. Will it work?

Assuming you have the 15x7 OE aluminum wheels, the 255's on the front would be do-able, the 275's on the rear, no. Otherwise, there should be plenty of room.

If it were me, I'd run the 255's up front on 15x8's and the 275's on 15x10's.

Agreed, after looking into it, and taking some measurements, both tires will fit with the correct rim size. The 255/60's will work on a 7-8" rim where as the 275/60's require a 7.5-9.5". I'm still going to squeeze the 275 onto the stock rim and see how fast the center wears. I'll post more later.

Tires now on the truck, 255/60 15's front and 275/60 15's rear fit on a stock 2wd setup with no rubbing. The front tires are slightly smaller in diameter and it is a little noticeable compared to the stock 235's but the rears look very similar (we're talking in diameter here).

yes they will both work on 7" rims but it is not suggested. when i first bought my 06 sport those are the exact size tires i had on it. you will get uneven center wear on your rear tires.

FWIW, STOCK new rangers come with 255's on 7's.

 

[fivemagics818]

keep in mind that those 255's are also on a 16 inch rim and they are 75 series tires and usually goodyear. goodyear blows lol

ummm.......rim diameter doesn't mean squat. it's rim width.... ALL stock wheels are 7" wide.

wasnt trying to start an arguement, i was just generalizing. like i said the 75 series tires makes a big difference as compared to a 60 series tire. the sixty series tire is going to be alteast an inch wider than even a 70 series.

I'm not trying to start an arguement either....

But you can't make posts like that without understanding how to read a metric tire size. Here, I'll spill it out for ya...

Tire in question: 255/70R16

255 = tread width in millemeters
70 = 70% of the treadwidth is the sidewall height
R = Radial
16 = wheel diameter.

If the tread width is the same(255), but the sidewall is different(say from 70, down to 60), tire height will shrink.

60 series or 70 series or 30 series tires have nothing to do with the width of the tire. BUT, a 60 series tire will look wider than a 70 series, because it's shorter in total height.

Again, not trying to start an arguement, just inform.

i understand how tire sizes are broken down. i work for a tire shop. a tire with a smaller aspect ratio but the same tread diameter is going to be wider its not just some illusion that makes the tire look wider. of course it will be shorter in overall diameter due to the sidewall being only 60% of the tread face rather than 70%, but the tire is still going to be wider. just to inform

 

[Fx4wannabe01]

How is the tire going to be wider if the tread width measurement remains the same and only the sidewall ratio changes?

 

[4x4junkie]

Yeah, I'm not understanding that either, a 255mm wide tread is a 255mm wide tread (if anything, the tire with the higher aspect ratio will have a wider overall width due to the sidewall bulge that sticks out further).

Ok, after 4000 miles there is noticable wear in the center of the 275's. Although it looks badass, I would not recommend using the stock rims for that tire size.

The situation is, width being equal, a tire with a taller sidewall (255/70) will tolerate being on a narrower rim better than a tire with a shorter sidewall (255/60).
