My rears are out...but my front have like 70% left...Was wondering any body mix/match their tires? I found some much cheaper (more quality) for the rear but it's another brand so threading is different...Traction/speed rating is actually better...Was wondering if different thread would cause any difference in handling/water dispersion ...thanks.

 

probably should not do that considering the tires are one of the most important part of your car, since they are the only thing in contact with the road. Good tires effect braking too so that's another thing you always want to consider. You may have a car that handles very unpredictably as well. You bought an S2000, you need to face the fact that it's going to cost you more than the average car to keep it in good operational order. Everything costs more to service/maintain. Don't skimp on the tires.

 

i understand about not skimping on the tires that's why those new tires are actually better brand than my front (front=falken, rear=Pirelli)...But your theory that handling may be unpredictable is very helpful...

 

Ideally, you should not have mix tires on front and rear if you are aggressive driver, who like to get close to limit on curvy roads, specially when it is raining.
If the Pirelli you are considering for the rear has better traction in both wet and dry conditions than the front Falken, then you will have more understeer than all 4 tires of the same brand. If you decide to go with Pirelli for the rear, then you should slowly increase the connering and stopping limits to learn how your car handle in both wet and dry roads.

 

i have been contemplating the same thing, i have T1S 245mm's in the back and T1S 225's up front, the fronts will likley go before the backs because i just replaced them. however when i get new fronts i wanna get the kdw BFG's, then eventually get them for the back also when its time to replace.

 

The brand of tire won't tell you how well it performs. You have to consider each individual model. For instance, the Falken Azenis RT-615 is a better performing street tire than anything Pirelli currently makes for street use.

I'd recommend against mixing a BFG KDW with the Toyo T1-S. I suspect that the KDW has much quicker response than the T1-S, and you'll end up with a car that turns in sharply, then the rear end sort of wags and wallows shortly afterward.

This is okay if you're just planning to cruise the main drag, but for any sort of high performance driving I'd want matched tires. You might consider that accident avoidance is a form of high performance driving...

 

The other problem is some tires just don't work well together and may make the car pull one way or another. It won't hurt the car to run mis matched tires but at the limit the handling car get a little scary.
If I can help let me know.

 

I'd be more worried about wet handling myself. Having your front tire hydroplane and your rears not... iew... or vice versa.

Or going around a corner with the fronts griping and the rears (which can break loose easily to begin with) go... or the rears griping fine and ugly understeer...
