Tyre wear

[Horney]

Hi Folks,

Right I did Silverstone on Tuesday and it killed my passenger side front as per the pic below.



The bald section is the outside of the tyre and this was the outside front wheel in all the long fast corners at silverstone.

I'm running about 1.5 Deg of neg camber on the Golf and had the pressure at 28psi when the tyres were hot.

I'm surprised at the wear due to it being so one sided. Should I be running less or more tyre pressure to try and even out the wear in the future?

the instructor was saying to use higher pressures at silverstone so im guessing higher corner speeds need higher pressure. i was running them at 31 hot and didnt get uneven wear, but then again you did have more tracktime than me. think im running less camber as well because its still running the least camber possible from when it was a road car

tyre pressure is a bit of an art though, im sure we will ruin a few sets of tyres trying to figure it out

a lot of golfs run 2 deg, might be worth a try

Yeah I was thinking more pressure to stop the tyre rolling over as I guess that's why the wear is one side only.

MKIII Camber bolts will be picked up over the winter for more camberz

Nick my friend who's done a lot of track days used to run her Mini's tyres at about 45 psi on a hot day so it may be worth going a bit higher. Her car never had uneven tyre wear (although it had been set up properly with corner weighting as well...)

you need someone to get your camera out and take a load of boreing photos of your car in corners.

passinger side frount is allways the tyer that 2wd hatches murder   if your pushing on anyway   but what you want to do is get a sequence of photos of the car enetering and going round a corner.  and zoomed right in on the car,  as long as you can see it's frount end tyers and track thats all thats needed

then you can see what happening,  your tyer pressures sound ok but i woud be running them higer but then i seem to prefer my car with very hard tyers for some reason. 

it looks like form that tyre you need to wind the damping up and add camber.       I ran 3ish degrees on mine for a while it woudl wear the inside down inpressivly quickly on the road but was right on the track,     i had it set to one degree as i was usiengi it on the road a bit much and in one day  knocked the outsides right down.

I had the dampers set to their hardest setting so no more movement available there. I reckon your right, more camber needed. Will get myself some MKIII strut bolts mine are pretty knackered anyway as the heads are all slightly rounded.

I'll try a high pressure on that wheel at the next trackday as well although that may well not be till the new year depending on funds.

turn the tyre round on the wheel and get another day out of it

Hi Chaps,

I too had some tyre wear on Tuesday -  Here is my front near side ;



I also had wear on the inside edge of the back offside, the front offside and the back nearside both look fine. I was running 27psi hot. I would have thought that running a higher pressure would have made the wear even worse.

I think that I may just put it on the back next time out.

Hey Ralph welcome to the forum. Your tyre wear looks much better than mine! Was an awesome day though and good to see the MKII Golf's showing the Porkers a thing or two.

Get some more pressure in them + keep checking pressure throughout the day.

I tend to run 35-45psi depending on the weather
