There is certainly some of that ^^

pps:
But tire manufacturers & the differences in their 'nominal sizes' don't really help either, despite the
supposed 'standardisation' of these nominal sizes!! You really
CANNOT rely solely on the nominal size printed on the sidewall when choosing alternative tires or on
ANY of the Tire size comparison charts or software tables on the internet. Sure, they can be a start, but too many manufacturers use all sorts of different methods to arrive at the size they put on the sidewalls of their various tires & the nominal sizes are simply the closest standard size under whichever method they use, and they use a bunch of different methods!! I've seen different diameters &/or widths of over 25mm/1 inch on different brands of tires that had the same nominal size printed on their sidewalls & therefore
should have been much closer in size than that!! And often those tires often show as being the same size on the internet tables, but in reality they can be significantly different sizes!!
Still, I for one have always been of the opinion that the
biggest 'nominal size' tire that's likely to fit up front on the 2013 or later Spyders without mods is a 175/
60R15; & have expressed here on SpyderLovers more than once my doubts that you could get a 65 profile 175 R15 tire to fit under the stock fenders without some touching or modification!! :shocked:
So with all that in mind, when choosing alternative tires you really
NEED to check/compare the
physical rolling diameter, the width, or at least the number of rotations it takes to roll 1 km/mile (ie, the circumference) on any potential alternative tire to make sure it's not
too different from the OE tire & is going to fit. Most tire manufacturers make at least one of those dimensions available in their technical specs for each different tire type & size they sell. Failing to do so means you stand a good chance of getting tires that just
DON'T fit or
WON'T work on your Spyder - & really, you should probably do that comparison when selecting alternative tires for
any vehicle!
