I think this may be a better way to compare tire sizes.

Good one rays hell, I've just added it to my bookmarks. Thanks, Treva.

Tire size calculators will give you a mathematical SIZE ………. However the actual size of any tire sold depends on the manufacturer. If you think every 165/60 - 15 tire is exactly the same - - - Well they aren't.... You really need to see what the tire maker states the dimensions are...…, Mike :thumbup:

You are spot on, that's why i actually went to the tire dealer to compare sizes etc. Thanks BK911.

I've just fitted the Bridgestone Potenza RE050A 175/55R 15 with no clearance issues at all. Fitted the Bridgestone Adrenalin RE003 205/55R 15 on the rear. Could have physically fitted a 215/55, but the aspect ratio/profile versus the front tires may have thrown the nanny into confusion.

I'm running 18/20 psi front/rear to start with but that may change. I cannot believe the difference in grip which is staggering compared to the kendras, along with straight line stability & braking. So good is the difference, i'm about to fit the same tires to my RT.

Anyone who hasn't fitted good car tires don't know what there missing. My only regret is not fitting them sooner.

I'm using your post as a quote, because you brought up the possibility of a tire size conflicting / upsetting the NANNY...….Because the Spyder suspension design restricts what tire sizes can be used, the difference between the front and rear tires ( even at extreme differences ) isn't large enough to Upset the Nanny. This is assuming you are using Stock BRP wheels or aftermarket that match the BRP sizes ……. Mike :thumbup:

Yes Mike you are correct. Since purchasing those tires & some more research, I've fitted 215/55 along with the 175/55 [ Bridgestone potenza ] on my RT & no problems. The 225/55 would have been ok also but for clearance issues. Thanks mate.

“The 225/55 would have been ok also but for clearance issues” ......eh? ......doesn’t that mean it would NOT have been OK, Trev?

Pete, I have built myself a '' inner guard '' ie a rock guard which is attached via 2 u-bolts to the rear shock mounting cross brace. Without the guard, I'am pretty sure you could squeeze in the 225/55

Ahhhhhhhh. Gotcha Trev......makes sense.......I bought a rock guard and it protruded a little into that space which is why I went for the 205 Kuhmo, just in case. :2thumbs:
