Re: Uneven tyre wear
Acutally, the passenger side tyres always wear a little quicker- at least in this country. I think it may have something to do with road camber. Usually makes 0.5-1mm tread difference over the tyre's life. In real terms, most tyres provide 5.5mm of wearable tread as they normally come with 7-7.5mm of tread depth new.
One last but important point is that many tyres (especially Asian ones) have features in the tread which wear out deliberately early. This can then cause, particularly shoulder areas, to look almost worn out. It can make a very large difference to how the tyre looks, and the only way to be sure is to get a tread depth guage. Looks can be very misleading.
For the purposes of MOT, a car tyre (1931 on, less than 7 passenger seats) should have 1.6mm of tread over the central 3/4 of the tread section. Any features which are not of full tread depth or are designed to wear out early are to be ignored. Because of this, I've found many people change their tyres whilst there are 3+mm of tread on their tyres very often. Now, I'm not going to start debating wet weather performance etc, but I thought this might be useful to some people- especially when a tyre tread depth guage can be obtained of £2. Personally, I tend to avoid tyres which have this type of half depth tread feature.
