what is the target hot pressure?

TIA.

GT3 Nut

38-40
Check Hoosier website. They have some good info.
They even say for heavier cars 43+ in rear but I don't like it that high.

Matt is spot on with the temps. I liked closer to 38 (even 1-2psi below) since 40 seemed to be the magical temp where things start to get really FUN! Slip Slidin' Away.......

thx guys

Jetmech

what are you guys paying for your Hoosiers? fronts ? rears?

LVDell

$1375 installed locally at Discount Tire.

forgot to add.....245/315 setup.

For my C2, I've bought rears (295's & 285's) for $300 and fronts (245's) for $275 + installation from Lynne at Topless Performance www.toplessperformance.com He's based out of Arizona but brings his mobile rig to the POC events. Basically, he matches or even beats Tire Rack prices by a few bucks.

what Matt and Dell said.

I'll just want to add in that a vital data point here is the tire temp when you come into the pits after a track session. Target should be 180-200 F across the tires.

My hot pressure is 38-39 on my suspension setup.

Based on my experience with the R6 a pressure above 40 and temp above 200 and they are getting really greasy.

Assuming R6, do you guys drive to the track with them (assuming dry condittions) like other rcomps?

LVDell

No way. You shouldn't be driving to the track with a r-comp tire to begin with. The tread is too small and prone to easy cuts, etc.. You really need to trailer your wheels. If you don't have a trailer there are some here that have a special "baby" tire trailer that hooks up to the back of their car. r-comps are simply that, NOT intended for street use.

In summer with fresh rubber I have been known to drive on R6s to the track (about 60 miles in the country). Wouldn't do that if the rubber was near used up or if it were cold or rain was called for. Just my 2 cents.

I also had a 993 a number of years ago that used R compounds as my daily driver street tire during the spring through early fall. I don't see a reason why a tire like the MPSC (r compound) can't be driven on the street. Isn't that the factory OEM tire for a GT3 anyhow?? I know lots of guys running Toyo RA1s, Nitto NT01, MPSC, etc on the street. Not an issue other than cold weather use and heavy rain if the tread is worn down.

No it's not the factory tire for the 996GT3. Yes, the 997GT3 has cups but they are in fact a different tire. You can run them on the street but that isn't exactly the smartest thing especially on a slick surface like the R6. Road debris will not be your friend and then you will be SOL. RA-1 is totally different than a R6.

I drove on a set of NT01's about 100 feet (driveway to trailer) and got a small screw in the tire (only about 1/4") but still compromised the rubber.

So, can you do it? Sure. Should you? No way.

Seems most of the guys running rcomps (MPSC and RA1/888 seem to be the most popular) around here drive to the track with their rcomps unless they're driving a sedan (M3, R32, or something) and can transport them in the car easily. Don't see too many GT3's being trailered in or towing a tire trailer to the track, in fact I've never seen anyone towing a tire trailer (although that might not be a bad idea).

But you say RA1 (NT01/R888 as well I assume) is totally different than the R6 - which is why I asked the question specifically about the R6. I thought it might have a little more aggressive compound and possibly more fragile for road use.

Mike,

When I run R888s or MPSCs I have no qualms about driving to the track. While Dell is right, R-Comps aren't built with the same durability requirements as the average street tire, i have been lucky enough for them to survive 150+ mile trips to VIR from Washington, DC and back. If you do get a nail or screw or something you are SOL. I definitely don't drive the hoosiers on the street. Just my .02.
