tyre wear
Does this tyre wear look dodgy at all? This is the rear left off my Indy after 3 oulton trackdays and 2 Silverstone trackdays.
Rear right is wearing right down the center also but not worn as much as rear left.
Cheers,
Bri

Is this query about premature or uneven wear?
Doesn't look that uneven, and the speed of wear would be down to driving style, temps and compound.
it does look 'fairly' even to me. Both look more worn in centre which would possibly point to pressure being slightly too high.
Has the car had a geometry set up?

I'm no mechanic but to me looks like excessive heat build up or drifting.
Your tracking ok?

Yeah i just wondered if it was a bit too uneven it being right down the center. I did wonder about tyre pressures, but i've been running pretty
low pressures so i'd of thought it would have worn the edges of the tyre at a lower pressure rather than the center.
JMD, definitely no drifting, but i would describe my driving as "committed" and the tyres do get rather toasty.
Geometry hasn't been done for a couple of years really, should probably look at getting that done at some point. The car doesn't handle
badly in any way hence the reason i've not had it checked recently.

Wear in the centre is usually over inflation

18 is high especially for the track,was it a hot day?
Very few things are "really" needed.

What temp did you measure pressure at?

I run mine at 14psi cold if not less, they Gain at least 2 or 3 psi after a hammering on track

You could always buy an infrared thermometer from Maplins, go drive the car on your next trackday and come off track hot and quickly measure
temperature across the tyre width. It is a good reflection of which part of the tyre is doing the most work. Can give over/under inflation information
as well as clues on camber and tracking.

R888 always wear in the center as far as ive ever seen regardless of what we have done in terms of pressures
