MR2 Mk 3 front tyre wear

Anonymous · March 30, 2004, 14:48

I have a 2002 Mk 3. I have bridgestone potenza tyres. I have notices the inside blocks on the inside (inboard) of the tyres are wearing away far quicker than the rest of the tyre. I have had the 4 wheels alignment checked many times at different places but its always spot on.

Has anyone else notices unusual tyre wear on there tyres of this type? It is worse on the drivers side.

What kind of allignment did you have done? Just the tracking or did it check for everything like the camber setup etc?

And no doubt you'll start getting the knocking/clonking noise soon....but that's another story s:roll: :roll: s:roll:

I have been having 4 wheel laser alignment. All looked very hi tech with computer screens etc.

Is it something that i would expect from rear drive car??

it checked the camber, slip angle caster the lot. All in limits

the rears yes, teh fronts less so.

However I would suggest it's due to the amount of neg camber up front. Within spec is a bit misleading as you could drive a bus through toyotas acceptabel spec range it's soooo wide.

If it is the reason they could reduce the amount of camber up front and probably still be within specs. It wil however change teh way teh car drives, whether for the better or worse only you will know.

You guys seen the negative camber on an F1 car?

IMH(and not very educated)O, I reckon the negative camber on the fronts helps the tyres "bite in" on when cornering.

my car does turn in well and handles exceletly. I have recently increased the front pressures to around 29PSI . makes front drift slightly under prolonged cornering with power on.

Given our rather dated suspension geometry setup, -ve camber is only as beneficial as the cornering load put through it. At all other times, it's not really a very good thing. I've you've got excessive -ve camber I suspect you will get pretty good cornering characteristics, especially if you have a maintained a stock suspension setup.

A combination of -ve camber, toe out and under-inflation can all mount up to excess inner edge wear. I suggest posting your actual alignment levels (did you say you had an '03 or pre '03?) and we can all give you some conflicting information based on our interpretations of it.

Possibly....check my thread 'knocking on full lock' as this has been covered many times before s:D

s:D

The good guys on here were a great help and I'm sure that Markiii could recommend you buy new Toyo Proxes s:lol: :lol: s:lol:

Hi,

Inside wear on the fronts in normal, as said above the front wheels are toed in (i.e when going stright the tyres run on the inner edges)

The reason, better grip in the corners. The Mk3 only has one normal setting, where as the previous models had various settings.

You should look ot get between 15 - 20 k out of the fronts under normal use conditions.....

THe first time I came to change mine, I thought, bloody hell, but the mechanic was unconcerned and told me I'd done well to get 20k out of them.

It's a caracteristic of the car, meaning better ahndling at the sacrifice of extended tire life.

Hope this helps.

Cheers

My stock Yokos have done 12,000 miles. The wear on both front tyres on the inside tread is considerably more than on the outside tread ( about 3mm difference between them) . Does anyone know if this is the normal difference expected?

darrenjuggins · April 5, 2004, 16:40

Yes, they run on the inner edge, not the whole tyre as in "normal" family wagons.

just how its set up for optimal handling.

Cheers

Now ditch your yokos and get some nice Toyo Proxys instead! s:twisted: :twisted: s:twisted:

I was waiting for that one. Thanks Kris s:roll: :roll: s:roll:

Unfortunately I cannot get Toyos as they do not make a 215/45 R16 for the 03 model. Are Bridgestone and Yoko the only two that supply both front and back sizes for this? The write ups on these two leave me uninspired. The car is only used on the road. Any feedback would be appreciated as a change is urgently needed.

Thanks

Change the sizes of the tyres. Ive got 195/50/15 & 225/40/16 IIRC and they are fine. The toyos are sooo much better than the stock yokos, much less snappy.

Quite a few people on here now have this setup and have no reported problems at all. My car handles like a dream.

Anonymous · April 6, 2004, 13:30

I take it that these sizes fit on the stock rims?

Anonymous · April 6, 2004, 13:31

yup, fit like a glove, no probs what so ever.
