20,000 miles and still have OEM front tires

[BajaRon]

Another good example. Kenda lists the 165/55R15 tire as having an overall diameter of 23" and section width of 7" . For the 165/60R15 Vredestein Quatrac, Tire Rack lists an overall diameter of 22.8" and section width of 6.5". Taking these samples into account, I should have zero clearance issues with the Vredestein. Yet, my past 165/55R15 Quatrac 5's did have a slight rub. I wonder if the specs changed between the prior Quatrac 5 and current Quatrac??

It's more likely to be the 'Where' these dimensions were taken. Could be another location on the tire carcass that is the difference.

We have had ZERO issues installing the Yokohama 175/55R15 on bikes of all years 2014 to current with all 4 fender types. Physical dimensions of different brands in the same nominal size run different.

How about on a 2022 RT S2S? These tires + mounting would run me $330 locally from a tire vendor buddy. I don't know if I want to take that much of a $$ gamble

Yes,

Yes, have installed many sets on 2020 to current RT. They fit just fine.

Just my 2 cents worth,
I have 175/55R15 Kumho's on my 2020 RTL, they fit very, very, close to inside fender.
I have 165/60R15 Continental Cont-Pro on my 2021 RTL, they fit "perfectly" (my next GO TO TIRE!)

Ron's likely got it there - altho 'When' during the manufacturing process might also come into play here!

Some tire manufacturers measure the tire carcass BEFORE the tread layers get put on in order to arrive at the 'Nominal size' they put on the sidewall; while others wait until the tread layers have been added; and others wait until the tire and tread is fully complete and ready to roll out the door!!

The differences in 'Where' they are measured can mean one tires size varies significantly from other tires despite them both having the same 'Nominal size'; the differences in 'When' they are measured can be even greater! The largest variation I've seen in rolling diameter (so far!!) from the 'Nominal size' to the 'Actual size' was juuust a tad over 50mm - all due to that specific tire manufacturer measuring those particular tires in a different place to where they usually measured and to where most other manufacturers measured, and to compound the issue, they measured at a different time in the tires construction process too!!

Can you imagine trying to fit a tire with a 50mm/2" larger rolling diameter to that of the recommended nominal size tires anywhere on a Spyder?!

I replaced my Kenda Kanines on front at 33,000 miles with Continentals. So far I like them.

As being reminded by Knizer, my past Vredesteins were fitted to PPA wheels. PPA wheels are 5.5" wide, while OEM RT wheels are 5" wide. That could explain things a bit clearer? Yet, I had no clearance issues with PPA/Vredestein on the 2019 F3S. Fitment issues could be wheel related?
