used Euromeister alloy replicas and went from 15" Phone Dials to 16" with 205/55 front on 7" and 225/50 on 8" rears. Fit/clearance ggod. Can anyone tell me how much this may affect speedodometer or other issues. Thanks.

 

Ithink I may be able to answer my own question - seems if increased rime size but kept the overall size of tire the same because I used lower profile tires, there should be no big change - what do you think Doc?

 

Correct.
