Michelin Tyres - Jamie

Hello Jamie,
Thanks for taking part in the forum. My e89 is now four years old, it had OEM runflat bridgestones on when I got it, and these were destroyed by cracked alloy wheels that haunted me later. I replaced them along with new wheels with runflat Pirelli P Zeros, which I thought were a bit worse grip in the wet but ok in the dry and had a shape less likely to wear on the inner as the bridgestones did due to camber.

I've lived with the P Zeros for about a year, they're run flats of course, and while there's loads of tread left, they're a hard ride which I want to rid myself of, and the risk of more cracked wheels which I put down to poor roads and runflats. I've finally shelled out £800 for four new Michelin Pilot Super Sports to be fitted this Friday by Event Tyres (mobile fitters).

My two questions are; 

1) are the Michelin PSS quite a square tyre like the bridgestones and am I likely to suffer inner shoulder wear like I did with the bridgestones or do they have a more chamfered edge like the P Zeros to help with the camber?

2) As I'm now going non run flat in the hope that the ride quality with improve, what would you recommend in terms of dealing with a flat if I get one. The 'goo/inflate' approach/recovery etc?  (the car has nowhere to store a spare tyre/wheel).

EDIT: 

I've a 3rd question ;) I note theres a fuel voucher promo on. I'm buying 2x 255 30 19 and 2x 225 35 19 but I note that the terms of the offer state to get the full voucher I need to get the same widths.. is this the case? Or will my rather expensive purchase qualify for the best voucher?

	Hi, Thanks for your query. I'm sure you will find a huge difference once the Super Sports go on.. To answer the questions, the PSS have a chamfered and rolled edge. But what is propably more important is the way the casing is built, compared to the competitor tyres. We have a more supple and flexible carcass, due to materials and techniques used, meaning the shoulder stresses and distribution of force through the tread will be very different. What I recommend to absolutely everyone, is to run your camber and toe settings as close to zero as the manufacturer settings allow. This gives your lovely new big wide tyre a fighting chance by running in a straight and upright manner. Improving grip and wear life. Most manufacturers have a tolerance for geometry settings, and while more camber might be good for mid corner grip at Donington, its fairly hard on the tyres of a road car. For a spare tyre solution, if you don't (or cant) look at a temp spare, then the sealant systems can help. The best advice really depends upon where and how badly damaged the tyre is. If you pick up a nail in the tread, and its a slow leak then they can be used, and if not run flat, the tyre more often than not can be repaired (after washing the goo out..). If its a ripped open sidewall, nothing will help, but then again if you rip open a runflat sidewall it would go flat too... The voucher applies based upon rim size, so with 4 17"+ tyres, the best voucher will come back to you. Don't hesitate to ask me any more.. Thanks Jamie

	All good feedback, thanks. I'm really looking forward to the PSS 'first drive'. I'll also check out local firms that might help me with the camber too. I think this is quite large presently at 5 degrees factory (rears) and this wore the rather square edged bridgestones badly on the inner. The P Zeros are wearing fine as their edge is much rounder, albeit with what looks like less contact surface. One other question if I may, the current pressures shown on the door of the car are 2,9 rear and 2,4 front (bar) should I use these same pressures on the PSS given they're not runflat?

	Best advice on Pressures is very much "suck it and see" Keep an eye on the wear, and tune it up and down from there. Pressures are always set for dynamic handling, not flat wear. but I'd start there and see how you get on. Don't be afraid with alignment to tell them what you want. As most places will simply leav it if it's within tolerance, as opposed to adjusting it to your own specs.. The non runflats may feel "soft" in comparison, just give yourself a few miles and hours to get feeling of total confidence back, as it will feel like a different car

	Well the tyres are on, despite one of my alloys being damaged by the fitter (£650 alloy sigh) and I have to say the decision and expenditure was worth it. The drive is so much more comfortable, there is a lot more feedback through the steering (low frequency which is good, all the high frequency feedback is also gone, great). Definitely worth the switch. Edited by Maniac - 06 Oct 2013 at 11:48am

	Dave, Yes sadly the 235/40-17 was made in sx mxx3 and then pilot sports for m3's but it's not a size we make anymore. There is the possibility to convert to a similar size, (225/45-17) which was a fitment, but that's up to you.. Let me know if there is anything else I can help with
