A4 Sline summer tires 19"rim hit pot hole on passenger side
 

Hi, everyone,

Would you mind to share with me how to deal with my old tires on driver side when I just was told by the dealer that my 4 tires need to be change after I hit the pot hole on the passenger side and rims are fine but both front and rear tires on passenger side are now finished due to side wall damaged.

Can I just put the old ones to the front or the rear and just purchased a two new tires?

The current tires are using since day 1 from factory, it is 255/35 ZR19, Dunlop Sport SP with 45+KM used.

Many thanks !! :D

Oh, sorry. I use winter tires in winter, so my summer tires just used 25+KM only...

25K+ km and not 25+ KM, sorry again for the typo

The reason is likely that a tread difference between tires is not the best situation for an AWD vehicle with a mechanical centre diff.

I would suspect that the dealer doesn't think that there is sufficient tread on the 3 good tires to make it worth replacing just one. Usually when that is the case, they "shave" the replacement tire to match the running diameter of the existing tires.

No point in shaving half of a new tire off when you can replace all 4 with new shoes.

Best bet is to but a tire depth gauge from crappy tire (about $5) and check for yourself. Most new tires come with 9-10/32" of tread with wear bars at 2/32"

Most people replace them between 2/32 and 4/32, unless they have a tread wear warranty like Michelin, then it is to whatever spec gets them the best deal on a new set!
