Hey guys sorry if this has been covered before however I'm in the middle of work and kind of need to know ASAP.

Well i just had a Blow out on one of my tires. And I'm gonna need to order a New tire for that rim.

Here's the big problem I know that is it bad for the Diff if the wheels do not have all the same Diameter. Would the tread difference be enough to mess up my diff? The other tires have probably right around 10-15,000 miles? I'm am not a real hard driver. Theres seems to be a pretty good amount of tread left on my current tires

basically should i order a new SET of tires or can i get by with just one?

Thanks,
Vince

 

That minimal difference can create some issues over time. Taken from our Tech Center article,

Matching Tires on Four-Wheel Drive And All-Wheel Drive Vehicles

...........As an example of different tire diameters resulting from tires worn to different tread depths, we'll compare two 225/45R17-sized tires, a new tire with its original tread depth of 10/32-inch and a second tire worn to 8/32-inch of remaining tread depth. The new 225/45R17-sized tire has a calculated diameter of 24.97", a circumference of 78.44" and will roll 835 times each mile. The same tire worn to 8/32-inch of remaining tread depth is calculated to be 1/8" shorter with a diameter of 24.84", have a circumference of 78.04" and will roll 839 times per mile. While the difference of 1/8" in overall diameter doesn't seem excessive, the resulting 4 revolutions per mile difference can place a continuous strain on the tires and vehicle's driveline. Obviously, the greater the difference in the tires' circumferences, the greater the resulting strain.

 

Neal is right. If possible buy the same tire that you currently have on the other three rims and have it shaved to the same tread depth as your remaining ones.

 

Buy 4 all new tires, its what I did...

 

We can street shave the tire(s) down for $25 each.

 

how do you do that? and how would you get it to match? would i just measure how much tread is left?

thanks!

 

We have staff that shaves street and competition tires on a lathe. Pretty cool stuff. Just measure the tread depth of the remaining tire opposite of the one you need to replace and I can it shaved.

 

what if it's not a tire you carry? could i send you a tire and have you send it back?

Thanks,
Vincent

 

what happens if you have to use your donut?

 

You have a good likelihood of breaking a diff if you drive on it for very long at all.

 

dont do the shave buy four new tires dont take the chance.shaving is only good if you buying and racing r compound tires for track.if there is more then 5/32nds of tread diff from any tires you will heat the diff fluid and cause damage.

 

dammmn are you guys serious.... every time there has been a blow out of flat on an evo ... we need to buy a new SET of tires ... asdfl;jcvwaeljjsfascasd

 

Uh. No. Stop scaring the kid.Even with 2/32nds of tread differential you can still wear a diff. Please don't post if you don't know what you're talking about.
No. Just buy the same tire as the rest of the three and have it shaved. It'll be fine.

 

I would replace them all. I was in about the same boat as you had one go out at about 18k on the tires. What I did as a band aid for the future is kept the three good tires and replaced all four with the same tires that were on there. So if this happens again I hopefully would be covered. From what I read you can only get away with 2/32 depth difference between the tires.

 

2/32 of an inch? or what i'm confused of this measurement
