I've only changed the fronts (as the rears had new Contisport N2s when I bought the car), so by all reckoning my car should be an uncontrollable death-trap.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Morning all. Has anyone tried non-'N' rated tyres, and noticed an actual difference in the car on the road? Pete

POST 2Original post

I had none N rated tyres on HD1 for a couple of years prior to selling it. I had Toyos (R1's I think not the slick R888's).......they were cheap (£700 for all 4)......they didn't have the same feel on the road as my previous PS2's (felt lighter) but had no effect on the performance etc and they were probably better wearing than the PS2's.......after 16,000 miles still had 4.5mm or more on all tyres when I sold it.....

POST 3Original post

if you still use the similar manufacturer brands you may not notice a difference but if you switch to a completely different brand you will some cheaper tyre companies do make some interesting claims, but most of that is clever marketing N rated Info http://911uk.com/template.php?page=3

POST 4 / ORIGINAL POSTEROriginal post

Being a born sceptic, I did assume that 'N' ratings were 'clever marketing' too! Am I right in thinking that neither Porsche nor the tyre companies will reveal exactly what it is that's different about 'N' tyres.....other than to make vague (marketing?! :lol: ) claims about ride quality and the like? Is my cynicism misplaced? :? I know this debate has been done to death, and I certainly don't want to go over it all again, but my gut feeling is that, in normal driving conditions, you'd be hard pushed to notice a difference. I just wondered if anybody had done! Pete

POST 5Original post

I think the main difference is that the insurance co can refuse to pay out if you crash and have non-approved tyres on it.... this is hearsay though, not confirmed. LOJO

POST 6Original post

yes - there is much more grip at the front with Vredestein Sessanta than with Pirelli Rosso N4. I've only changed the fronts (as the rears had new Contisport N2s when I bought the car), so by all reckoning my car should be an uncontrollable death-trap. They can't refuse if I make a claim - because I've already asked them, and they don't care if they are n-rated or not.

POST 7 / ORIGINAL POSTEROriginal post

The wife's insurers, Norwich Union, also have no problem with non-'N' tyres, although they did say they would (quite rightly) require speed/load ratings to be appropriate. Pete

POST 8Original post

Though to be fair thats mainly because the Rossos are so flippin' awful. Same for me, no issues from my insurers. I run Toyo R888s on my track wheels and they are ace.
