Michelin sport 7?

[paddy1000111]

Hi all,

Had a pretty rubbish experience at 70 this morning when my v6s decided to fishtail up a hill on the Motorway, luckily pulled it back and had a quiet drive the rest of the way. I'm going to get some better tyres than the p-zeros. A friend of mine has fitted the sport contact 7s to his M4 and has nothing but good things to say. Anyone else got any experience? I don't fancy shelling out for PS4'S

Baby it's cold outside

Conditions are out of any UHP tyre manufacturer recommendation as far as I know. How much tread do you have left on the Pzeros? Mine have been excellent but they're at 7mm at the front and 4.5mm at the back. The Jag is enjoying a week off this week though.

Glad you're OK.

As far as I know there aren't any all season tyres for our cars so just summer and winter tyres and you'll need to swap them over every year, or use a different car in the winter.

Thanks, I even had it in ice/rain mode! If it wasn't for a clear lane each side of me and a bit of luck I wouldn't be looking for new tyres but a new car. I think I down to 3.2 on the back but they are the wider 295/30R20. I did notice the continentals were quieter and a better fuel rating but the same rating for wet weather (A) so how much I'd really gain I'm not sure

Michelin is only up to 5 for the Sports, I think you mean Continental?

I think a new set of performance tyres would provide enough grip improvement. I looked into the Crossclimate sizes available but Michelin does not make them in that configuration.

I'd choose the Goodyear F1 Asymmetric 6 personally.

at 3.2 they need changing

I had a lovely slide on cold tyres the other day on a small roundabout. Felt like prime Ken Block. These Conti SC7 tyres seem to be winning all comparison tests but on different sizes than would fit my SVR. I'm not sure they do 305/30 for my rear tyres not sure on 295 tyres though.

Haveing a limited slip differential has many advantages overall but the 1 disadvantage is that when the rear wheels break traction, they both break traction, causing a slide. This is a good thing if your into drifting however!

Certain caution must be exercised when accelerating with both rear wheels on a
very slippery surface. If too much throttle is applied, particularly when cornering,
lateral stability will be lost, and the rear of the car will go into a slide. This occurs
when both wheels spin together without differentiation (i.e., the clutch capacity exceeds
the road's ability to induce differentiation).

Interesting point. I'm happy with my bog standard mechanical diff.

Apologies, yes I do!

I completely agree, it's in for a service next month so I was going to look at tires at the same time. Thing is, the road was dry this morning, i just want something that's a bit less slippery. It seems to regularly break traction on dry days between 20-50mph during gear changes which is poor I think as I often have to let off, regain traction and then go again.

This is the thing that threw me off guard, it was in ice/rain mode, it also wasn't a hard acceleration at all, it didn't change up gear as far as I remember. I was actually dropping it off at the specialist for a new water pump this AM. I got picked up by a family member who's Nissan Xtrail slid on the white lines in the road so I think poor gritting and -6 weather is to blame for a large part. I just don't want to spend ~£300 per tyre on something that could be better in a similar price range.

I've only used ice/rain mode once, in my previous XKR, and it made the throttle so unresponsive that I ended up almost spinning in a car park. I now prefer to rely on my normal throttle muscle memory to adjust for conditions!

maybe it doesn't help, I have noticed that it just adjusts the curve as opposed to limiting the overall power. It can lead you into a situation where you accelerate and want more power so you apply more throttle thinking its linear like normal mode and its quite a steep throttle curve past a certain point.

I'm not going to make excuses, whatever I did was my fault but I think better tyres would lead to more of a safe zone for errors. That being said my poor grip at the rear probably prevented me from getting catapulted into the central reservation when I was facing it at one point

Yeah, I found the throttle so unresponsive that I pushed it harder and that spun up the rear on the slippery surface - I found it hard to judge how much throttle to apply to get the power I needed. I guess for it to be useful you need to practise beforehand to understand exactly how it affects everything. But who's going to do that on a dry day in an F-Type? :lol:
