7.5inch wide rims on Yeti?

[BJ75]

Thanks Brad. It's still an option if the swap doesn't come through. Part of me prefers the R-Type rims - every time a see a Scirocco with a set of black ones I picture them on my car looking quite sharp (but the shorter ones obviously).

I guess my concern is the fact that these are replica wheels, not made by whoever makes VAG/Skoda wheels. So I wonder if I'll have balancing issues, or if they're just crap quality.

Don't suppose you know if putting 235/50 tyres on a 7.5in wide rim would affect the speedo? My inferior knowledge is that if the profile (the 50 part) is the same, the overall diameter will be the same. But I don't know for sure if that's right.

Is 235/50r17 the standard size that came with the vehicle? If so, the difference in OD when on a 7" rim & a 7.5" or 8" will be negligable. They are good for a 6.5"-8.5" rim

Standard tyre size for the Yeti on Spitzbergs is 225/50r17. Not sure how much of a difference that makes.

Yeah the standards are 225/50 as Rooboy points out. I guess my thought was that in getting a slightly wider rim, I wondered if I should get a slightly wider tyre to match. It's probably not necessary, but in case there was a reason I HAD to get the 235 to match a 7.5in rim, I wanted to know if it would affect the overall diamater and thus the speedometer.

But it looks like the 225 will be fine on a 7.5 anyway.

The aspect ratio or profile (in this case, 50) is expressed as a ratio that's derived from the tyre's section height / tyre's section width x 100.

So given the same aspect ratio, if you change the width, so will the height. This ultimately changes the overall diameter (OD).

For instance, a 225/50 R17 tyre has an OD of 658 mm and a 235/50 R17 tyre has a OD of 668 mm.

Fitting a tyre with a bigger OD will make the speedometer less overestimate the indicated speed. The wheel width does not noticeably affect the tyre's OD.

Increasing the wheel width by 0.5" and increasing the tyre width by 10 mm does not usually cause concern in most cars.

No, it's not necessary. A 225/50 R17 tyre can be fitted on any wheel with a width of 6.0 to 8.0.
