Here's a thread I made a while back on TPMS relearn tool if you don't already have one and want to find one for cheap!

update: i did the tires and added 100+hp at the same time. i have more tail wag going on than before. enough that when i am wot i get worried around 100mph and let off. i am running 35psi in the tires.

the car had a little tail wag stock so i am guessing it is the extra power more than anything but i am not sure of that, maybe a combination of the power and tires. time to do more research and probably buy more parts.

How warm was it when you tested and noticed this? These tires like temps to be at least 70F I've heard. Also isn't 35psi high for these?

I figured 35psi would be a good place for driving around pressure. I would like to know what other run when they are not racing. I have had these tires before and left them at 20psi all the time and it ruined the sidewalls before the tread was gone.

It is cold here. Probably 30deg last night when I was testing. Tires were 70deg when I left the garage and I was only out an hour. It would be unfortunate if this is the cause, the tires definately hook much better than stock even in the cold and we sometimes race in the cold. Hell I have been to the track when it was 40deg before.

I haven't put mine on yet because of the snow storm, but my local shop told me I should be running them around 25psi. I thought that was low for DD and figured I'd do exactly what you're doing, unless I wanted to play.

Yeah the temp thing I've read in a few places and I'm pretty sure applies to all R compound tires. Also keep in mind that while while your garage is one temp, the road is much colder. You can't even just go by the outside air temp. Early in the year the ground will be a lot colder. I've also read that these tires need a good burnout (4 or 5 seconds) if you really want them to grip, especially if it's on the colder side. I know it's not what you want to hear right now but once it warms up these tires will make a huge difference for you. For early spring and fall though you might be better off with a Sport Cup 2 or comparable street tire. That's why I'm going to keep my PSS tires on until we hit spring and start seeing temps in the 60s on a regular basis.

just to be clear the tires hook great even in the cold, even without a burn out, even at 35psi. way better than the stock tires. I am just looking at the tail wag issue right now.

If it is the tires causing the wag I may have to consider an alternative.

[LesBaer]

Sorry man, I don't know enough yet until I can try them in optimal conditions. Is the tail wag happening on straight pulls or when you take a turn? Try lowering your psi to see if that helps.

I think the issue was the temperatures. If the outside temps were 30s and the ground about the same you'd have issues even with the OEM summer tires.

I'm not an expert in DRs but I know that for just summer performance tires they say that under 40 degrees out you aren't supposed to use them, the rubber gets so hard (and plastic like) that they will slip and slide and wag ect. I'd assume DRs are very simliar. On a 50 degree day, I'd guess you'd have to either to do burnout or drive on 50 degree pavement for a while to get the tire temperature to equalize to the ground.

The wag you are experiencing could also be the cradle bushings, they are pretty soft I am told.

FYI I have the same feeling over 100 with my pss 305s. It does not inspire confidence at all. I'm not sure if it's all the power or the tires or.... No idea. Temps were in the 50s and 60s when I did my testing.

[parish8]

I plan on buying most/all of the bmr stuff. They say that will fix the problem.

Hey I'm sure you did the wire relocation but have you had any other issues and how has traction improved ?

[LesBaer]

Oh yeah I forgot about the bushings. That's probably why I never had that wag happen at all on my car after adding the blower since I got the BMR arms w/bushings done with it. I've gotten the car up over 150mph on 305 MPSS tires and she was very steady.
