I don't think he is... Mike, the problem with your guesstimate is that it's based on nothing. Your assertion that the tyre is only 10mm wider so it's not possible to feel a difference is silly - the next step is a 185, can you then tell the difference from a 175?, then it's a 195, can you then tell the difference from the 185? And so it goes on. At what point does the straw break the camel's back and you can tell a difference?
I've previously mentioned to you that I run the Vredestien tyres on my 4x4 and I find they aquaplane noticeably earlier than other tyres I've used and I backed this up with a tyre report. I realise this was a bit inconvenient for you since you actively promote that tyre but, hey-ho, it's an open forum for discussion. I will say this to you though, I do believe the Vredestien tyre is a very satisfactory tyre in dry and wet road conditions, just not in flooded road conditions.
.. Dear Lady please tell All of us exactly what " tyre " doesn't aquaplane " In Flooded road conditions " …. Your Maxxis ?????
Looking at the Vredestien tread, you will notice that the side blocks of the tyre are linked by a solid section and this will give improved stability to the tread blocks but it'll be at the expense of water removal out between the side tread blocks so the only exit for mass water is through the central grooves. Although you diss the Kenda tyres, look at the tread and study the water removal routes and, particularly on the rear tyre, the amount of drainage both to the rear and the sides of the tread. One disadvantage of this is the rear tyre actually has a limited amount of rubber contacting the road so it's life is rather short.
Absolutely it is.
Well it will if your tyres lift off the road surface on a wet day!
Lastly, there seems to be a general notion that wider tyres are automatically better, well It ain't necessarily so. And for that reason I run 155's on the front and 205's on the rear, and I can tell you that the VSS has kicked in and backed off the throttle a number of times in high G corners in wet road conditions.
All IMHO, of course.
