Car pulling under acceleration

Soapy water is pretty special. I'm just being sarcastic.

On a related note, OP, RE003's are directional.

Pic reference. It has an inside and an outside tread block.

They will have to be re mounted correctly.

Cheers.

There is directionality with respect to the rim, and there is directionality with respect to rotation.

This tire does not care which direction it rotates.

I've seen directional tires mounted backwards and it causes feathering of the tread blocks. When turned around and mounted the right way, the tire has a vibration and chops real bad which causes further damage. It depends on how aggressive the tread pattern is, but the damage can happen quickly.

They're all mounted the right way. It has inside written in huge letters on the inside so it's impossible to miss. The tyres seem to be asymmetrical which means the outer tread faces in different directions on either side of the car. In order for a tyre to be directional doesn't the tread have to be symmetrical like the Advan ad08r's?

There's a special goop they use on the bead to lube it up when they mount the tire to the rim. If they use the wrong goop or none at all, the tire can be damaged internally and show nothing outside. The fact that the pull moves with the wheel tells me that this issue is tire or rim related.

You might have a bad rim or one that can only be road force balanced. Find a shop to have the wheels road force balanced and inspected carefully (with the tires not mounted to them so they can look at the inside of the rims). Have them dismount the tires and remount them- all of them, don't be cheap. If the tires were incorrectly mounted, it may be reversible. You could have gotten a bad tire too and you'll just have to try to get your money back on it.

If it was alignment, the problem would persist no matter what position the tires are at. Like others have said though, if the tires are directional, if one is mounted in the wrong direction that might be the problem. Running a few hundred miles on a directional tire mounted backwards can also ruin that tire.

I shall take the car to a place near me and get them to inspect the rim and tyre properly. Shall report back with news if it's worth reporting

If they tread faces opposite ways, that's your problem. Whoever mounted them, mounted them wrong.

Check all 4 corners, you may be lucky and you have them swapped on opposite corners. Otherwise, if not, the only solution to that is to pull the tire off the rim and remount it.

There will be a tiny arrow indicating direction of rotation , but it may be on the inboard side if the tire is backwards.

On the inside of the tyres it has INSIDE written in massive bold letters. Impossible to miss. Can't change them around. They're asymmetrical. Tyres have to be symmetrical in order to have a certain rotation as far as i'm aware?

I googled those tires and saw some pics. I didn't see if they are directional but they have an inside and an outside like @Midjetv8 says

I will confirm that our RE003 and the new NA market Firehawk Indy 500 (sharing a tread pattern) are Assymetrical and non-directional. as long as the larger treadblocks (denoted by an outside and inside label) are on the correct side, they are mounted correctly and can be rotated to any position on the vehicle. directional tread is symmetrical wrt the centerline of the tire.

Besides tire pressures, I am not sure what else with regards to the tire could cause your pulling issue. I would try looking into the alignment again

i always come into these threads hoping the OP is stock but that is never the case around here

Because people with problems with stock ones just quietly take them in and have them fixed under warranty.

This is good advice, possibly save yourself a headache and more money by trying another shop. Iv'e been down this road before only to find out that a different shop has found the alignment to be WAY off.

Yes. Thanks for clarifying.

I just though he may have had some inside sides on the outside.

I suppose not. Back to square 1.

Ya I thought we had it. At this point I think he needs to look elsewhere other than just focusing on tires. Could have a bad damper, improperly seated spring or any of a 100 other things with the modded suspension. We all got so wrapped up in the tires that we are totally overlooking many other possibilities.
