So I need four new tyres, rears are 285/30/21 and fronts 245/35/21, I have P Zero at present and I can get Michelin super sport for the same price, but what load rating? I can get 96y, 98y or 100y, what to do? Thanks Ian
Can you get a non runflat with the same load index as the runflats listed? Are they the correct size? should the rears be a 275/30 19 98Y?
Continental contact 6 105y rears, 100y fronts @ camskills - £832 Though historically continentals have softer compound https://www.camskill.co.uk/m74b0s10905p152386/Continental_Tyres_Car_Continental_ContiSportContact_6_Continental_Conti_Sport_Contact_6_-_285_35_R21_(105Y)_XL_FR_TL_Fuel_Eff_:_E_Wet_Grip:_A_NoiseClass:_2_Noise:_75dB Re getting the correct speed and load rating, I’m sure if you run a tyre search for 20” it will give you the correct data, safe to go up but not down I believe.
Looks like they’re still a 10J rim on the rears so you could use either size. Personally I like the super sports although they’re being replaced with pilot sport 4s now which is what I had to have fitted a month ago, superb tyre. Conti’s can be hit and miss on bm’s so I wouldn’t risk 4 of them but if you’ve been on Pirelli’s and we’re happy enough then I’d stick with what you know.
Yes, rears are 10J and fronts are 9.5J. Should I just go with the plate on the door shut even though that is for runflat?
I bought Michelin Pilot Supersport in the end, £941 from Black Circles. I will have them fitted at the weekend and report back. Ian
With the E60 and the F25 - I tend to up the psi by just 2 from what is recommended on the B pillar (run flat to normal tyre conversion). Still have/had even tyre wear and longetivity
Yes, that's what I do. My F10 has been on non RFTs since 2014 with no problems and wear rate is what I'd expect. My space saver spare has been used a couple of times though!
Had them fitted today and immediately the steering felt lighter and the ride seemed better (as good as it gets on 21’s). I had to wash the car though as the fitters left the tyre lubricant all over the wheels, cheap enoug though at £33 for the four at Costco.
Now four days in and the Michelin’s seem a little noisier than the old P Zero, but the ride is better and the steering feels sharper, but that may just be the result of new tyres regardless of make. One thing I have noticed is that the rim protection is much better on the Michelin’s, which is good on such low profile tyres. Overall I’m happy so far.
Just out of interest @kleynie, were the Michelins * star rated? I guess it's not that important unless you have an xDrive.
That's a shame as I've generally fitted Michelin Pilot Sports in the past, usually supplied and fitted by Costco, which were unbeatable for price. With my xDrive though, I wouldn't want to risk transmission woes by using non BMW rated tyres.
There are star rated ones in some sizes as the M cars were on them as standard figment although they’re being replaced now by the Pilot Sport 4S
