Am getting major rear tyre wear especially on my inside rear and on the inside of that too. I am running 20's lowered 40mm. Is this normal?
Not really gonna have any effect on the rear, and is looking at toe.Hi ,
You should really get your van laser aligned after you've lowered it ,
I didn't straight away and I was ripping the inside of my tyres out .
Best thing I've done , handles a dream T:
Great replyA: My van is wound right down on coilovers with 255/35/20. When I had the coilovers fitted I didnt get the tracking/allignment done and it scrubbed the inside of all 4 tyres (the rears to the wire) in no time I bought 4 new tyres and had the geometry set up, and 6000 miles later there is no sign of the inner edge scrubbing. Im not saying its not going to, just that tyre life can be prolonged with a few tweaks. *<>Not really gonna have any effect on the rear, and is looking at toe.
If your wheel is sitting exactly vertical to a level surface this would be 0 deg camber as the suspension is lowered or pushed down by weight the suspension will pivot and the top of the wheel move in this would be negative camber. This is moving the contact patch from the center of the tyre towards the inner edge, most vehicle have negative camber to help with cornering but obviously the lower you go the more negative the camber and the more the contact patch moves over the edge of the tyre. Then its going to wear more, much more.
The lower the profile of the tyre the less lateral flex there is in the tyre. The flex in a high profile tyre would allow you to run more negative camber than a low profile tyre. The sportsline runs on 45 profile tyre with a drop of only about 30mm??? you would think that VW have calculated this to not adversely knock the camber out so far when allowing for the max payload of the vehicle.
If you go to a good tyre fitter they will be able to measure your camber and tell you what it is they will also have what it should be.
If you go too low its gonna eat your tyres unless you buy camber adjusters but a low van does look the nuts and a 30mm drop still allows you to fly a plane between the tyre and the wheel arch.
You may have to live with the tyre wear, you could if the tyres are not directional have them turned around on the rim so the inner edge is now the outer edge. Depends how much a tyre place will charge for this as to whether it would be cost effective mate??
Tyre wear is the price of vanity! Of which I am guilty.speaking as an engineer who has been doing conversions forever, it is generally reckoned in the trade that if you modify one thing, 3 others will be a problem. thats why i havent lowered my van and get 45000 miles per set of tyres, all worn down within 2mm of each other and no shoulders worn off. simples!
Good to hear T:All sorted today and the moral of the story is!.........
If you lower your bus the very next thing you do is a a full geometry check. The toe in was miles out!! I was virtually dragging my rear wheels along. Still some camber there but hopefully tyre wear will be massively reduced.
Thanks everyone for all your help and advice.
PS mentioned camber adjusters/shims to VW commercial centre and they said they had never heard of them.
