V50 rear negative camber

Hi Iain, yes I understand how and why the tread wear would be more even, I was wondering if you've found upping the pressure has increased tyre life or if it just means the centre of the tread is wearing at an increased rate more inline with that of the inner tread of the tyre?

Not sure how to know that. The tyres now wear evenly so would imagine they last longer. Previously they would have to be changed when the inner edge was worn down. The centre and outer still had pleanty of tread left. Now they wear evenly so therefore must last longer.
I am on 17" rims and the ride comfort is still good.

I guess if you've been running those pressures for a while and weren't really interested in tyre longevity it would be difficult to know. It just interests me as I said earlier high pressure usually increases centre tread tyre wear but it's definitely something I will be trying.

As a bit of a gauge, FWD cars usually wear front tyres a lot quicker than rear tyres (at least all the ones I've had) but whenever I've had front tyres changed I've always been advised the rear tyres are close to being worn out at the same time due to the excessive inner edge wear.
I've done about 80,000mls in my car, and have so far replaced about 28 tyres. Two unnecessary due to new wheel size and a few puncture/pothole damage, but a lot of them due to high rear tyre wear rate (and I have had 4 wheel alignment checked)

That would explain why the garage always inflate new tyres way above what’s stated in the manual. Who knew national tyres were Volvo experts! Best go and put that air back in.

this is ironic. I was literally yesterday following a v50 thinking it had nutty negative camber at the rear!

Yeh . . That's just the way we roll dude

Measured the distance between ground and top of wheelarch earlier, at 675mm. I did have maybe 5kg of tools in the boot, but no dog guard or parcel shelf.quite a way off the distance measured for the t5 AWD earlier in the thread, if that helps.

I feel pointed out and probably offended, sir!....
(but jokes aside damn, thats over 50mm difference... im high, and in the wrong way :P...)

Good, you top of the range snob
I am on 120k, and thinking about changing the rear shocks for some bilsteins, so if it's dropped a bit I don't know, but not by 2"

It's not unusual for your car to be higher off the ground than lower spec, 2wd model. Different car I know, but I have an Impreza WRX, and know for sure they are 25mm higher than the sport/GX model.

my rear end has a 2 degree camber angle.

I run them on 38-40 PSI and I have very even wear on the tyres. Running on low pressure will result in uneven wear. So recommended to run them on quite high pressure, depending on the tyres too.
