The Blue Meenie Posted July 9, 2011 Report Share Posted July 9, 2011 (edited) Use to run Goodyear on my '99 Mono Sports on the ST, and their pressure was 36. Moss's have now put new Pirelli P6000 205/55 R16 91W on all, except PSR (just noticed this is 205/55 R16 91V today) on these alloys, for everyday use - running on a Gen 6 GT. Originally they said to pressure them at 34, but I was getting slight wobble at 70, so they've now suggested and dropped the pressure to 32.... Alls fine in the dry, but got a bit of a shock Friday on the way home. There was surface water... but not masses, as the rain had stopped a couple of hours earlier. I aquaplained slightly at 50 just joining the dual part of A64... everyone else were managing ok with speeds of 60 and over... My questions are.... Does 3 tyres with 91W and 1 with 91V (Passenger side rear) make a difference? What pressure would everyone else recommend for these tyres? Does under pressure give less grip in wet? (as I aways thought it was over pressurised that caused slides) This incident freaked me out, and dont trust these tyres in the wet (bought them 23 April 11), so would like to get this sorted asap Just found out these are reknown for it .. see link http://www.tyrereviews.co.uk/Tyre/Pirelli/P6000_2.htm Edited July 9, 2011 by The Blue Meenie Link to comment Share on other sites More sharing options...
Monkey_matt Posted July 9, 2011 Report Share Posted July 9, 2011 Quick search online and it seems that P6000 are deadly in the wet, alot of people are complaining about lack of grip in wet conditions, so think that would be the problem Link to comment Share on other sites More sharing options...

Monkey_matt Posted July 9, 2011 Report Share Posted July 9, 2011 http://tinyurl.com/3nuckur just read the links, alot of tales of aquaplaning, being lethal in the wet, no grip, dont even need to enter the sites, just read the lil bit that comes up on the search!

paulgtt Posted July 9, 2011 Report Share Posted July 9, 2011 Does 3 tyres with 91W and 1 with 91V (Passenger side rear) make a difference? the W and V are the speed ratings, i think W is 168mph and V 150mph, won't make a difference to grip level.

tctech Posted July 10, 2011 Report Share Posted July 10, 2011 p6000 s are pretty much lethal in the wet ,too hard a compound but as a rule tyres for the wet are pressured slightly higher than in the dry 2-3 psi or so the reason for this is that the tyre is expanded slightly more so puts a wider tread area on the road .it is however a trade off between grip and sidewall deflection ,if the tyre is pressured too much then the sidewalls can be too stiff and as tyres are an integral part of the cars suspension pressures affect handling Link to comment Share on other sites More sharing options...
