I got some new tires for my g35 rims and now i have really bad wheel hop. Tire size is 235/40/18 with a treadwear of 380. What would cause this? The low profile of the tire? I had it before my new tires so i got the nwp torque link and it took it away completely. Do i have to re adjust the link? I have an 03 6sp with lsd if that makes a difference. Thanks in advance for the answers!

um your new tires just grip better than your old.

Wheel hop is just the struggle between the tires trying to hold onto the road and the motor trying to spin......This is just a fancy way of saying your car doesnt make enough power to cleanly spin the wheels so its rapidly gripping/spinning and causing all kinds of rawkus.

when the tires wear a little it will go away.

uh oh don't let planecrash005 see this he will just say you gained 40 hp ...

equal tire pressure between both sides? just throwin it out there.

also cold weather limits grip.

When you introduce a sudden application of torque through the drive train, the weight of the engine will shift. I believe in the transverse mounted engine, forward gears make the engine rock towards the front of the car, and reverse will make the engine rock backwards, towards the firewall. Have someone watch your engine shift about as you goose the throttle while in gear, but with the brakes on.

Anyway, along with a whole bunch of other factors (tire pressure, tread wear, road debris, temperature), this weight change can cause wheel hop. And is more likely to do so if your engine mounts are old and sloppy. In other words, you might be a candidate for new engine torque-mount bushings.

Someone with a better understanding of the physics might be able to explain it better (or correct it).

True he said it happened after his new tires thou and he is a torque link.

The TL shouldn't be used as a fix to old engine mount bushings. But you're right, if he has an engine brace, that should keep it from rocking front to back.

I'm going to take a look at my engine mounts, but i think they're ok. If it was my mounts wouldent it have done it before the new tires too? I'm also going to try and adjust that torque link. And tire pressures are all ok. i'm just hoping it's because it's super cold here in wisconsin. (a high of 5 degrees yesterday)

I adjusted that link on my lunch break and it helped a little. But its still there. Maybe ill try the washer mod. Or maybe its my struts and its time for coilovers (at least thats what ill tell the girlfriend) lol

Our cars are bad wheelhoppers. ES mounts will help greatly, and also subframe connectors.

Wheel hop is usually caused by overinflated tires...check the pressure in the tires...

Pressures are all fine. I did the mounting and balancing at my work ( I work at a nissan dealer) adn they're all set at 35 psi. And what are subframe connectors? never heard of them

ive had more than a few sets of tires on my car and some seem to have bad wheel hop (kumho) and others dont ( bridgestone pp)

Better grip during hard acceleration now have exposed the your struts or engine mount are capable of handling the acceleration load....so it time to go the Illuminas and poly Motor Mounts.....
