Best quote bought and fitted locally £626, not too bad and about £200 pounds cheaper than the Michelin's.
I considered the Goodyears then read [url]http://www.talk.tyrereviews.co.uk/Article/2017-Auto-Bild-UHP-Tyre-Test.htm[/url] and plumped for the Vredestein Ultrac Vorti's as they came out better than the Goodyears and beat the Michelins in both wet and dry braking distances. The only thing that let them down are the rolling resistance (fuel economy) but what the hell :rofl: . Purchased online from Camskill in February this year the 225/35/19 fronts and 255/35/19 rears came in at £462.20 delivered to the door in 2 days. A bargain IMO :thumbsup:
I had the Vredesteins on my old 3 series and they were great. Nice and sticky but only managed 10k miles out of them.
That tyre test is a little out of date now as quite a few new releases came after that test, this one includes the newer tyres on the market. [url]http://www.talk.tyrereviews.co.uk/Article/2018-Auto-Bild-20-inch-UHP-Tyre-Test.htm[/url]

I notice a lot of folks are running wider tyres at the rear which presumably increases grip but are there any downsides (other than cost)?

Increased road noise and cost. The jump from 255 to 275 gave quite a jump in road noise for me.

The extra grip does outweigh the downsides in my opinion.

At the moment I have 225 all round. I think the max my rims would permit would be 245. Does the wider width also give more protection to the rims?

Not such a bargain then after all! :lol: Still, 10k miles will last me 4 years so they'll be due a change anyway :wink:

I wouldn't oversize the tyres on the wheel. I only use 275 width because I have 10j width wheels.

This may have been covered before but what do you guys with non run flats do about punctures?

Definitely thinking of changing eventually but at the moment all four tyres are about 15K miles from needing changing.

Well mine isn't an E89, but in anticipation of switching to non-RFTs I bought 2 cans of Holts Tyreweld and a 12 volt compressor.

As I have an E86 I also bought a 17" spacesaver, jack and wheel-brace from a forum member as Plan B.

RAC membership as Plan C. :lol:

Thanks, Rob. Were 17s options on all E89s?

My car had 17 all round and changed to 18. Running Goodyears. Can't rotate the wheels now, front and rear different sizes. And have a space saver in the boot as my cars a commuter. Still managed to get two soft bags in there for holiday, obviously no roof down.
Most punctures, like the one i have now are slow to release air and have known about it for a month or so now. Just keep topping up as i am about to fit two new rears before mot, just trying to get the most out of them. The tyre fitter i go to suggested not to use the goo in the can, as it makes a right mess for them to clean up.

I'm looking to replace my nightmare runflats with PilotSport 4s. Can get a set fitted for 466 quid with BlackCircles, 40 pounds off if you buy 4. Do I run them at a different pressure to that recommended for the runflats?

Oh no, here we go again, general opinion is about 3 or 4lbs less than runflats pressures, but don't ask Busterboo or you'll get a totally different answer. :evil:
