Tyre wear and replacement tyres

Post by ori » Sun Jul 31, 2022 4:07 pm

Yeah. Rescuing the tread starting depth is equivalent to using smaller packaging on food.

I’ve got ages on my tyres as during my recent incident bmw measured all my depths and said they are over 6mm.

Need to drive the car harder. ;)

Tyre wear and replacement tyres

Post by Nanu » Mon Aug 08, 2022 8:24 pm

Just picked up this thread and find the tyre wear scary. My old e89 gave me 20k on the rears and half as much again on the fronts. Was expecting similar mileage out of the current ones on the G29. Sounds like I may be disappointed :o

I would be looking if there were any replacement RF's that gave a less harsh ride. Finding the Michelin’s about the same as the old Bridgestones.

Nanu, what pressure are you running in the G29? Having had both the options you’ve mentioned I wouldn’t even class them in the same ballpark. If your Michelin’s are comparable to your old Bridgestones there’s something not right imo

    Running then as prescribed on the side of the foot panel which is 2.3 bar.

    The ride is firmer than the 35is but I understand that is the nature of the beast and the larger tyres.

    I found the 18" Goodyear F1 A3's RSC's that I fitted to the 435xd were better than the standard Bridgestone's RSC, however now that you've found the goo go for a more comfortable conventional tyre. Are you running 19" or 18" wheels?

    I got something like 8,000 from the rears on my e89, so I reckon you'll be fine with the g29.

    Andy mentioned not going above 3k revs, but I would imagine it's more the low down torque that wears the tyres quickly - quick starts from standstill or slow speed.

    I'd give another vote for the Conti 7s - I haven't once come close to losing traction at the back since I put them on, but maybe I'm just not trying as hard as I did when the Michelins were on!

    Like most, I'm not pushing my car anywhere near it's limits, but I'd still happily pay more for that 2% extra grip for when I make a mistake or encounter an unexpected situation.

    Now come on Will, you of all folk should know better than that :rofl:

    The 3k revs were for the first 1200 miles while running it in, the rest has been a free for all as soon as the engine is heated up :thumbsup:

    And I’ll give feedback on the Conti’s after the NTNC500 next week :driving:

      We’ll see how the Conti’s go, 6.8mm measured on the rears before they went on :cry:
