Tires

[Strenoob11]

So i had funny situation. I felt vibration on highway so i went to balance wheels. At workshop it turned out i installed the tires wrong (245/40/18 front and 225/40/18 rear) because previous owner didnt even mention different width and i didnt pay attention. Problem is that at workshop they put wider tires to rear as it is supposed to be i think. Now it feels like car is always pulling somewhere. I dont know how to explain it. Its like its gripping every curb.

How far had you driven with the tyres incorrectly placed?  Are the tyres even on the correct rims?  The wider, rear tyres are also on slightly wider rims.

If you’ve had the wheels balanced then the tyre pressures should have also been checked.  If you open the driver’s door there should be a tyre information panel near the door lock.

You might have to consider having the tracking checked.  Look for uneven tyre wear across the tread and signs of scuffing - all indications that adjustments are needed.  If it’s been MOT’d recently then that should have exposed any general wear in the steering and suspension that might cause it to run down into the camber of the road.

Correct tires should be 255/35/18 rear and 225/40/18 front

I think i drove it with incorrect placement like 2500km. Checked pressures they are okay.

Just noticed that you’re non-UK so my MOT comment is probably not valid!  But if by ‘gripping every kerb’ you mean that the steering tends to drift excessively down the road camber to the kerb, then that could well be down to incorrect tracking - possibly caused by wear.

Considering what else has been happening, you might also check that the front wheels are pointing straight ahead when the steering wheel is central!  After all, it’s possible that the car suffered some front end damage and repair before you got it?

it is still very funny problem, because when the tires were wrongly installed it was good to drive. Now when wider tires are in the rear it starts pulling. And that happened immediately after switching tires (wider to rear)

Pulling - or drifting - to the left and/or down the camber is most likely related to what’s going on with the front wheels.  Again, this could be the result of tyre wear, tyre pressures, tracking problems, steering misalignment, rubbing discs and such like.

My point is…it’s not so much that the wider tyres are now on the rear (which they should be) but that the narrow tyres are now on the front AFTER 2500K running as rear tyres.  Depending on how enthusiastically those 2500K have been driven, they might well have been subjected to wear and stress that changed their performance relative to the wider tyres.

Apart from getting tyre/wheel/suspension specialists to check the car,  a close inspection of all the tyre treads might show a different wear pattern for the now fronts as compared with the now rears!

Or maybe someone else has a better idea?  🤔

Just noticed that you’ve mentioned the tyre sizes, but not the brand.  Well here’s another thought…are they asymmetric?  Are they directional?

It could be that you have the two front tyres on the wrong wheels.  If they’re asymmetric then the tread is in blocks, with the larger blocks on the outside.  Often the word ‘Outside’ is on the tyre wall.

If they’re directional, they’ll have a V tread pattern and an arrow on the outer wall indicating the direction of forward motion.

Getting this wrong might well produce the effect you describe.

This article explains it in more detail.

The outside letter is written outside of the wheel as installed. I went to alignment garage and everything was ok. In there they told me my car pulls because i have wider tires in rear and it isnt mentioned to be that way and estonia roads are not that good. He couldnt explain how i disnt have any problems when tires were incorrectly installed. After that i went to that MOT check or sonething and he checked all the bushings and suspensions and stuff and everything was in good condition. Maybe it really is because of vad roads here. Im out of ideas myself.
