Hi,

One of the tires on my car has a bubble on the sidewall.

1. Is it advisable to just replace one tire? If not, should I replace 2 or all 4? My tires have about 20,000 miles on them.

2. The current tires are BFGoodRich 195/65-15. Is it advisable to replace them with wider tires for stability? If so, what size would be good?

3. Any suggestions on which brand of tires are good?

thanks in advance
cheers

 

If you just replace one, it'll likely pull to the side as you drive. You'd have to be very careful about an EXACT match & then they won't match tread-depth anyway.

Buy 2 & keep the spare somewhere?

Buy 2 vs 4 is sort of a judgement call. How worn are they? 20k miles means they just might have way more than 1/2 of their life remaining. (Depending on lots of factors)
