F / R different tire makes?

osbornsm · 03-26-2015, 10:01 AM

SO i went cheap with my 1st set of track tires... I bought some Sumitomo HTR III in stock sizes.

Realizing these will never live up to my expectations... i'm going to upgrade to Michelin PSS next.

Question: Can i replace JUST the rears with PSS until the fronts wear out?

Or is that wacky for handling?

Discuss.

I highly recommend all 4 tires are the same brand ESPECIALLY if you are going to the track.

MagmaRed370z · 03-26-2015, 10:04 AM

yup me too. Go 4 corners with PSS

Masterbeatty · 03-26-2015, 10:13 AM

Yes, the handling characteristics will be VERY unpredictable and IMO unsafe.

m4a1mustang · 03-26-2015, 10:13 AM

Never mix. Replace them all.

osbornsm · 03-26-2015, 10:19 AM

Guess i'll have some fronts for sale huh.

FAIR ENOUGH. I'm not a big fan of the Sumitomo anyway.

osbornsm · 03-26-2015, 10:22 AM

p.s. How much Michelin PSS can i fit on the Base wheels anyway?

Currently I have:
- F: 245/45/18
- R: 275/40/18

Thinking of going to:
- F: 245/40/18
- R: 285/35/18

Why Michelin PSS?

There are better tires for cheaper than those. Hankooks, BFGs, Bridgestones...

Hankook RS3s in 275/35/18 are $245 on TireRack, just get 4 of those.

For DD two diff types of tires that are close in tread and rating is OK-so so, not a great idea, but I have done it with no problems for two years now.

For track, you definitely don't want to do that.

osbornsm · 03-26-2015, 01:40 PM

Is there something against the Michelin PSS??

I thought they were the sh*t for traction.

Have there been better track results with a different tire?

"Good" tires available in my ideal sizes are...

Hankook Ventus R-S3 (Version 2)
Michelin Pilot Super Sport
Dunlop Direzza ZII Star Spec

GSS138 · 03-26-2015, 02:23 PM

The UTQG rating of a tire will generally tell you what class of performance a tire is in. PSS are 300-which is nothing special, it's a high performance street tire. It's over priced for what it is in addition. My personal impression of it is that it's atire primarily aimed at douche bag Bimmer owners that want to hard park at their office buildings. It's really not a track tire.

Go to any auto-cross or track day and take a look at the tires being run by the experienced guys (not including DOT R-Comps). You will see Dunlop (Star Specs), Toyo (R1R), Bridgestone (old RE-11A and now RE71R), & BF Goodrich (Rival)(sorry if I left out your favorite). But you never see Michelin or Goodyear.

Why? I can only guess. For competitive drivers $ is never the issue. It is about lap times.

Nicely put... although i think i'm looking at RS-3's for next track tire.

On a road course, I can respect wanting the same compound front and rear since you will see greater variances in temperature, and you want the F/R bias to be consistent. For the street, there is nothing unsafe or unpredictable about mixing. I never have the same tires or even remotely the same compound front and rear for the street and the car is extremely predictable, consistent, and confident.

takjak2 · 03-26-2015, 09:56 PM

As phunk said, there is nothing inherently wrong with different tires front and rear. With the PSS only in the rear you'll just be inducing understeer.

For street tires on the base 18s I think 255/275 is ideal.
