Boro Posted March 10, 2009 Share Posted March 10, 2009 I have noticed that the nsr tyre has worn on the inside inch or so considerably more than the rest of the tyre, what could cause this? obviously want to sort this before i fit the new tyres Quote Link to comment Share on other sites More sharing options...
dantd5 Posted March 10, 2009 Share Posted March 10, 2009 Check upper swivel pin and bearings. Could be a deformed or Knakkered bearing causing it to twist in a bow-legged fashion!! Quote Link to comment Share on other sites More sharing options...
cipx2 Posted March 10, 2009 Share Posted March 10, 2009 I think nsr tyre means near side rear tyre, so no swivels to check. You should go and have a full geometry check on both axles. What make/model is the tyre, how old is it and for how long did it stay in that place (rear left side) in case the tyres were rotated? Any other tyre with abnormal wear?

Yes i do meen near side rear, geometry check would be expensive (i know from having cars done) is there nothing simple i can do myself as i dont see the point in paying to have a check if shortly i will be replacing bushes etc which will change all the readings anyway, note although the bushes are old none are truly shot that i can see, tyre is a goodyear wrangler all terrain, no idea how old as i have only had the vehicle for 9 months, tyres have not been rotated since i have had it, not noticed any other uneven tyre wear Quote Link to comment Share on other sites More sharing options...
cipx2 Posted March 10, 2009 Share Posted March 10, 2009 The reasons you have one tyre on the rear axle unevenly worn could be - and how to check: - the camber angle on that wheel way out of normal values (bent axle or stub axle) - alignment check - there is a toe in/out on that wheel (bent axle or stub axle) - alignment check - might be a case of axles not paralell (the rear wheels don't follow in the same tracks as the front) but this usually involves the other tyre on the rear axle wear abnormally but not so unevenly - alignment check - the wheel was put in that place (rear left side) after it wore unevenly while it was place on another corner (like on the front axle) and the cause could have been corrected by now or not - alignment check - the tyre/wheel comes from another vehicle (bought used as a replacement) - you can check the manufacturing date and serial number on the tyre and compare them with what you find on the other tyres - DIY job - the tyre has a manufacturing defect (less likely but possible) - no one can really tell if true or not (maybe if the alignment proves ok). If I were to be in your shoes I'd do this: - replace what you have to replace on the vehicle except tyres (by the way, replacing the bushes won't affect wheel alignment) - do a full 4 wheel alignment check - further actions depending on the alignment test; if alignment ok => new tyres; if not => replace what's bent or it's not right. A quick search revealed that prices for a full 4 wheel alignment check is between £45 and £65 at independents and wheel specialists. You can even get a free alignment if you buy a new set of tyres. Is that too expensive? If it is too expensive than start reading the theory about wheel angles and alignment and do a search how to DIY (you can find even youtube videos). The results and precision will be good enough if you do it right. Quote Link to comment Share on other sites More sharing options...
Boro Posted March 10, 2009 Author Share Posted March 10, 2009 I will take some measurements in relation to the front axle and see what its like, having rebuilt the rear axle last summer with new stub axles, bearings, hubs, discs and pads (and all associated bits) i can happily say its not a bet stub axle, the osr wheel bearing failed (hence i rebuilt the axle) when i say failed i mean it would bind as you took off or stopped in traffic and made an unpleasant noise whilst on the go, this was about 2 weeks after i bought it but im just trying to think if the previous owner had been driving it with a bearing that was catching whether the tyre on the opposite end of the axle would wear, good call on the tyre possibly being on the front, now you mention it i think theres a good chance it could have been on the front in the past, btw local alignment place charged me £90 last time i went there granted there are very few places around here that like doing proper 4 wheel alignment and they did do a damn good job!
