Hello Gary ..

I read this on yokohama webstie i can't understand it well

Choosing a wider rim: increases vehicular stability, steering response and cornering ability. A rule of thumb is to use a rim width 90% as wide as the tread width (not section width) of a performance tire for street applications. This provides a good balance between performance and ride quality. Always be sure that the chosen rim width is within the tire's range of acceptable rim width specifications

I have 16" x 7" wheels
i mounted 205/55 R16 tires on them

7 inch = 177.8 mm
my section width would be 205 mm

177.8 /205 = 86 %

would that be a better setup than mounting a 225/55 R 16 on the same wheel

177.8 / 225 = 79%

i mean what setup is better 205 or 225 knowing that they have nearly same diameter .....

The fact is that the 225/55R16 end up being nearly an inch taller overall, not suggested. Use 225/50R16 if you're after a wider tire with about the same OD.

I wrote 225/55 by mistake
i meant 225/50 R 16

but what do you think of this 90% tread width NOT section width Notion ...
is it true in this case ?

if we chose wheels that are 90% as wide as tread width .. what benefits ?
better handling
and how can we measure tread width

when they say this tire fits 6-7.5 RANGE
what is the best place in this range ? middle ? end of it ? start of it ?

225/50R16 not even an inch wider, so while in theory it will help a bit in handling, its considered mostly a cosmetic difference. As long as you're in the rim width range you won't see much difference in handling on street applications. Since you're already changing tires though, may as well go wider if its not gonig to be used in the snow.

No best wheel width IMO. If you're on R compound ultra stiff race tires shoot for the higher end of the range in general. For street tires, makes very little difference. :thumbup:

Gary,

I am about to purchase the 225/50 R 16s to replace my OEM 205/55 R 16s. These tires will be used in the snow. Do you recomend the switch? Will i run into any problems? Please advise.

Thanks

Mike

225/50R16 is slightly wider so not quite as good in the snow, but the difference isn't much (less than an inch) and should not cause problems.
