do non runflats grip better during acceleration?

If I go past 3/4 throttle at a stop sign or light, I"m lighing up the front tires pretty bad

it really kills the off the line performance, I get wheelspin in 2nd too unless the road is perfect


I also have a big problem with these stock runflats pulling the car all over the road, any imperfection in the road and they torque steer all over the place, only bothers me on straight line accelerations

Car does have an LSD, ordered anyway, I never check to make sure it actually has one

FWD + lots of torque/HP == wheelspin. Stickier non-RFs might mitigate that slightly, but I think you'll just have to learn how to launch it. LSD will help with wheel slippage in corners, but out of the hole, it's not going to do a lot to decrease wheelspin. Pretty good read here:

stickier tires. you'll see a 100% improvement in all aspects of the car's performance.

I'm not sure I know how to launch it

if I punch it in 1st, with no launch wheelspin, it will simply start to spin around 4500 rpm

even in 2nd I've done it

The tires are that bad. Trust me. Anything stickier will be a huge improvement.

One thing, though. are you 100% sure your clutch isn't slipping?

Clutch slippage would result in reduced (or zero) wheelspin...

The classic clutch symptom is slippage. Engine revolutions are not fully transferred to the transmission. Power is not fully transmitted to the drive wheels. The engine seems to race but the vehicle does not keep up! Slippage is most often caused by a worn clutch disc.

I know that, but what I'm saying is, he may not actually HAVE wheelspin. If the clutch is slipping, the car will rev without accellerating, and that could FEEL like wheelspin.

I think his tires will have to be really, really bad for the car to break loose like he is describing at higher speeds. My car with an open diff and all season run-flats won't break loose in second or third unless I REALLY dump the clutch on a shift.

Ah. Gotcha. Yeah... could be, the engine would certainly sound the same... rev, rev, rev, catch.

no clutch slip, and the tires squeal when they break loose and lay down black marks

the tires are OEM runflats, 12,000 miles on them


I've never dumped the clutch, EVER, all wheelspin is from flooring the throttle after the clutch is fully disengaged

That's a bit long in the tooth for the OEM runflats. They wear pretty quick. At 18k, my 2004's were pretty much bald. Swap for some sticky rubber, and you'll be golden.
