[urq] tires and premature aging

[John Koenig]

With due respect to tire and wheel manufacturer's recommendations, etc., the 215 on an 8" Ronal was an (Audi) factory set-up from '84 on, right? 
In my experience, the concerns about too little section width and rim scratching are valid.

Myself and many others have run 215 width on 8" ronals for tens of years without any issues. The only downside I have seen is that the rims are more prone to scratching and such. When I bought my car the track instructor I got it from had 215's on it w/ the 8" ronals......painted black as some folks remember

Most tires have specs on allowable rim sizes. If a manufacture says it's 215 is good for 6 to 7.5 inch rims, in theory you should not put it on a 8 inch rim.

Why is the 215 width too narrow for the 8" ronals ? 225 would be better, agreed, how about unplugging the speedo transmission box for a few drives and use gps for a speedo to correct for the premature aging...... I wouldn't worry about aging you would need to put a lot of miles on the car to affect the value, especially since it's not original and not a 20v. 100k miles shows up as 105K, big deal. That would be 10+ years of driving for most urq owners. But yes, it would be nice to have an off the shelf perfect solution......i'd like to find some 15" wheels to fit my f-150 so I can get super deals on mud terrain tires for it.

Hi Lino, 

My drivetrain is now different from the original. When I swapped the engine from my '87 5kcstq, I also swapped the 016 transmission. Instead of .78 5th gear, my 5th gear is now .73. 

By 
undersize, I'm referring to the 205-60/15 tires that came stock on the 5kcstq. According to the 1010 tire calculator (205-60/15 stock): 

215-50/15 = -4.95% undersized, no tires <--This is causing my speedometer to run faster hence the premature aging. 
225-15/15 = -3.35% undersized, a few tires 
215-60/15 = +1.9% oversized, many tires available 

Of 
course 205-60/15 would be just right but are too narrow for the 15x8 Ronals. I would need to switch to 15x7 Fuchs, but I love the look of the Ronals. 

Tony
