All good then, and at a good price, however from personal experience and that of some others on here, the only way to get rid of speed range vibration(say 75 to 85 mph) is to use a 5 stud balancer rather than a cone balancer which mounts the wheel in the centre hole. This has little relation to how the wheel bolts to the car.

  Wim have invested in an automated tire changer to avoid wheel damage and 5 stud balancer, the only way to guarantee a truely balanced wheel ttbomk. If you had been to Wim you would know it is not a rip off.

But if your happy with your local fitter then fair enough.

fair enough my tyre guy uses the centre bore and i have to say ive never experienced this speed vibration.
my previous car was a VTi-S and i had new Goodyear Eagles fitted for a trackday with no problems....i got her to run off the clock at 145mph too with no vibration.

from what you say though, using a cone balancer must come down to the skill of the user...in which case hes pretty good!!

and the centre bore of the wheel, i fail to see how it has little relation as how it bolts to a car. if the hole on hte wheel is too small, it wont fit, if the hole in the wheel is too big then you get an awful vibration as the wheel moves very slightly on the studs (so my tyre fitter said, this comes from fitting wheels to an old car that had to have spigot rings fitted to elimate the vibration)

Well, did my usual commute today with chrisgixer's tyres on the front. Initial impressions were that there's a bit less weight to the steering meaning a little less feedback. More of a need to concentrate on the road rather then drive by feel although that may simply be due to a change in a setup I had got very used to.

Maybe it's very slightly more inclined to go wayward when hitting ruts and odd cambers but it's not as bad as I imagined it might be.

Overall grip is a little less than the SP Sportmax's meaning there's a tendency to understeer as the limit is approached. Ride is also a little harder, in fact I'm inclined to remove a couple of PSI of tyre pressure and re-evaluate them.

Yep all rings true really Kev, the ride is too firm due to higher pressure used to keep it straight, as you say. Try them at 32, which is the pressure i had been using. Then try to imagine your car with 2 rears as well giving the same feel.
  
Yours i think all fit in with what your saying, they are a little bit noisier with better grip, the ride with Dunlops is better than mine at 36 but not as good at 32. (Although your suspension is far better)

They feel more planted with a firmer more consistent feel at the steering wheel, which i think I mentioned to you as we left your house. This, i think, is the main key difference, esp re my issues.
There has been some reaction to road surface but nothing as drastic as the falkens, although the rear still pulls around as you would expect.

Interesting to see what happens when 2 new Dunlops are fitted and then i get the falkens back.

See how you go at 32psi Kev, should be....intersting.
