Car pulling under acceleration

There are 2 possibilities. 1) OP is wrong and the pull didn't change sides 2) The OP is right and the pull did change sides therefore the suspension can't be the problem.

Unless when the wheels were swapped around they swapped the dampers too.

Ahhhh I missed that line!


Shit, back to square one AGAIN.

I suppose not. Back to square 1.

Not necessarily. We've clarified but the condition has yet to be verified.

I did as well. Thanks, guybo. If the direction of the pull follows a particular wheel, that's a strong indication of tyre mismatch.

OP, are all four of your tires mounted properly on their wheels? Are you absolutely certain they are all the same size?

edit: ok, a lot happened since my last visit. Meh, I summarized.

All the dimensions and sized printed on the tyres is the same. Have it booked into a different tyre shop to get them to uninstall, check everything and reinstall the tyres. Shall report back if I have any luck! If not i'll live with it until I wear through them.

Just an FYI even if the tires are directional and you mount it the wrong way, it won't make a difference performance wise in dry conditions. It only starts to get hairy when you get into wet/slippery conditions with directional tires being mounted the wrong way.

Yeah in autocross, I'm told people run their RE71Rs backwards on dry days to even out the wear. No idea if it's okay to do, but I suppose that's a different circumstance than putting tens-of-thousands of miles on a DD tire.

Just a quick update, problem has been fixed. Swapping the front right and the rear left corrected the pull. Car feels mint now. Bridgestone tech couldn't give me an explanation as to why. But it works so it's all good!

Won't this be a problem again when you rotate your tires?

I'll tackle that hurdle once I get there. I'm just going to enjoy the car for a bit first.

My guess is that even though the tires may not be directional they all still need to be mounted with the tread in the same direction. Swapping two opposite tires would have reversed the direction on both and now they match the others. There is nothing else it could have been.
