Tyre wear

[Fox1429]

Hi,

Just wondering if anyone else has experienced the same issue.

I’ve noticed that my front tyres are wearing more on the inside quarter of both tyres.

I check the pressures and make sure they’re correct on a weekly basis.

I have the standard Bridgestones on the car (which have lasted 13000 miles thus far so can’t conplain about that) but the outside/middle tread is at 3mm but the inside is down to the markers.

Is this normal or do I have an issue?

Cheers.

what is the size you're using of both the tyres and the rims and what pressure are you using?

That seems to be the way the 6c is setup is it wears the inside edge.

at least it gives gives you a reason the get rid of the awful bridgestones

Standard tyres 215/40 17 (6C GTI)
39 psi front
35 psi rear
As per instructions.

As long as it’s not something wrong with the car I’m happy enough to have got 13000 out of the tyres.

Wanted to check it wasn’t just mine - do you think it is worth mentioning during servicing (due next month)?

For a GTI I'd say that you are taking an awful risk running with tread depths as low as that, especially at this time of year, normally you will find that GTI versions have slightly shorter and stiffer coil springs, now with simple suspension designs like that on the Polo, shorter springs will always mean a trend towards more -VE camber, which leads to uneven tyre wear. I'm guessing if you check the factory specs for GTI against that for lesser Polos, you will find that the front camber spec will be slightly towards more -VE - that is unless VW Group are using different lower arms on GTIs in compensate for the shorter springs.

BTW there is normally a trend towards more -VE front camber on cars had have higher engine outputs as it improves road holding, but higher engine output models also tend to have wider tyres, so when taken together uneven tyre wear is one of the outcomes.

In contrast, my daughter has a late 2009 SEAT Ibiza 1.4 16V SC - so that is a normal or low powered engined car with normal length front springs and wide tyres, and it wears all its tyres evenly across the wide.

Wear on both tyres on the inner edges suggests that the vehicle is toeing out too much. Go to a reputable garage with modern equipment for a check and correction.

That would depend on if the wear was jagged/toothed or just tapered wear, I think that you would feel the difference if you rubbed your hand over the surface of these tyres.

Rum4mo,

What would each of those types of wear indicate?

[RUM4MO]

Serious tracking errors normally leads to "toothed" pattern on treads, ie if you rub your hands over the tyre, round the tyre front to back or back to front, you can feel the tread pattern gripping your hand. In my experience, and you could argue that a tracking error or a camber error both end up with the tyre not being "true" to the direction of normal travel, with only a camber error, the tyre wear is uneven but "smooth" across the tyre, more like a taper/chamfer over the inner (or outer) 1/3 of the tyre width.

I have done 10k miles and the difference between outer and inner tread depth is 1mm. I do a lot of dual carriageway and motor way journeys so not as much cornering. Probably worth checking wheel alignment when you get new tyres. Speed bumps and potholes can throw out the tracking.

Thanks for all the replies.
I’ll get the tracking / alignment checked when I change the tyres.
