Non Matching Front And Rear Tires Question

[Michael Blazevich]

I have a 99 mustang gt and I am replacing all four tires. They are staggered, is it okay to get summitomo in the front and mickey thompson in the rear?

Please don't cheap out on tires because the front is where a lot of your braking power goes. I don't want to sound like Im lecturing you but its something to think about.

Well I now just realized when the front tires came in today.. I thought for a second thinking if it mattered or not before I put them on Friday

From what I was told if you go to small up front or too tall in rear (18 and 17) it will throw the abs off.

I run a slightly taller tire in rear but not by much and haven't had an issue. 315/35/17 and a 255/40/17

 

[Michael Blazevich]

I have 275 35 in the front, 315 40 in the rear

 

[Mineral4.6]

What size wheel?

 

[Michael Blazevich]

17"

Are the 315/40's DR's?? I couldn't find a 40 series ANYWHERE in any brand.

 

[Michael Blazevich]

275/40-17 front
Sumitomo high performance HTR Z II
315-35-17 rear
MIckey Thompson street comp tire

There's nothing "wrong" with running different brand tires like that nor does it pose a safety threat. I personally would be driven crazy looking at different sidewall lettering & tread patterns when looking at my car. My only question to you is- how wide are the rear rims that you're mounting those 315's on? Ideally you should be mounting those 315's on at least a 10.5" wide rim for safety reasons. I know that many guys have mounted a 315 on a 17 x 9 factory rim but you're going to have a lot of sidewall bulge which will harm your contact patch to the road effectively negating the purpose of a wide tire.

I almost purchased 275/50's for front but they are slightly taller then a 315/35 and I've heard of ppl having tracking issues so I ordered the 255/40's and I'm pretty happy with my choice. My 255's have slight run at full lock when turning. My wheels are 10.5 and 9.

 

[Michael Blazevich]

Yes I have 10.5 width in the back. So it seems that it'll be perfectly fine putting these tires on without any driving issues.

 

[Mineral4.6]

I think it's totally fine, but those rears won't last as long on the street. I personally like big and littles for a track set up. Fat rear with a skinny front rim/tire.

ok awesome ill let you know how it rides after the tires are on Friday

Besides not being able to rotate the tires, you should be o.k.

Going from stock 245/45 to the 40 series is quite noticable in ride quality, specially with lowered springs. I feel...every...bump in the road.

I left the stock tires, Rear adjustable swaybar, full length subframes, Roush front swaybar, KYB shocks, and I feel every bump in streets.
