tire size help!

[luv2liv]

my tire size is 225 50 R 17
i got an used tire from craigslist....and without realizing it... its 225 50 RF 17

would that matter???
cant seem to find anything on the difference between R and RF.

Are you trying to run differant tires on each side or are they the same brand and one has R and the other RF?

You can run differant tires from the front to the back but each axle should have the same tire.

RF is just reinforced sidewall. What brand is it? I thought RF tires are usually for trailers or special purpose.

Replacing one tire on AWD is generally not a good idea.

Why would your LF be worn out?

 

[luv2liv]

LTC my LF is worn out because its the oldest tire at 40k miles.
for some reason, i keep getting bubble in the tires....so the other 3 were replaced at different times. only the left front is the one with no bubble since purchase.

are you saying i cant replace just 1 at a time?? i have to replace all 4???

 

[Vette73]

No you can replace them 2 at a time but they have to be on the same axle (Front 2 or rear 2).

Don;t mix the tires from side to side. And best tires go on the rear.

With AWD, I believe you have to replace 2. You don't want a worn tire paired with a new tire.

Check your owner's manual to be sure.
