This thing was there in my mind while purchasing new car as I like big tyres (like all
) and family choice SsangYong Rexton had 16" alloys while TF, PS, XUV all had 17" & Hyundai santa fe had 18" alloys.
While searching more, I found internationally, SsangYong Rexton lower variants have 16" alloys with 235/75 or 255/70 tyres, while higher variant had 18" alloys with 255/60 tyres. In India, Rexton all variants come with 235/75 R16 on 16" alloy wheels.
Now can I change stock wheels to 18" alloy + 255/60 tyres, without any problem? Should I import 18" alloys from SsangYong or can go with any 18" alloys available in India?
I am not worried about speedometer if odo speed will differ, as I can have speed & km info from GPS unit (might not be exact, but who drives as per ODO. We usually drive as per traffic or road conditions permit, except at high speed limits). But whether such wheel change (if wheel change is exact as international availability or as per Indian availability) will affect
fuel efficiency,
ride & handling quality,
braking abilities,
suspension parameters etc.

Thanks for the link.
While doing calculation on posted link, result is
Tire Size Comparison
Specification Sidewall Radius Diameter Circumference Revs/Mile Difference
235/75-16 6.9in 14.9in 29.9in 93.9in 675 0.0%
255/60-18 6.0in 15.0in 30.0in 94.4in 671 0.6%
I think 255/60-18 will appear wider & but no big difference in size (as wheel size is increased 2" but sidewall decreased 0.9*2=1.8"), but what difference made between small alloy size + larger tyre profile & large alloy size + small tyre profile, as regards to ride, handling, brake, suspension, FE - for any car, except look if difference is minimal.
