A few questions, one of my rear tires is basically bald and the other is still good this is due to when I had to replace one when it got a flat and wasn’t repairable. The other still has pretty good tread depth. I read about replacing tires in pairs but is it really necessary or can I just replace the one? Right now I have continental tires. I was looking at a tire called general g max all season 05. Does it really matter getting a different brand tire which would be different patterns in the rear and it this a good tire? And last, do I need a wheel allignment?

Replace in pairs. It’s only about safety.

I strongly recommend those Generals, but why if you’re in sunny Florida?

What are the reasons to replace in pairs? One of my rear tires is still good. What would happen not replacing both? And that tire is only $170. Do you have any other recommendations?

On a front- or rear-wheel-drive vehicle, similar guidelines apply. If half or more of the tread on all four tires is gone, replacing just one tire will result in one wheel spinning at a slower rate than the others, possibly sending false signals to the traction control and antilock braking systems. It also will result in one tire having more or less traction for acceleration, braking and cornering grip than the others, which can affect a vehicle's behavior. On a two-wheel-drive vehicle, regardless of being FWD or RWD, a better approach would be to replace the pair on the same axle. The best approach, though, is to replace all four if the tread on the old tires is significantly worn.

If you decide to replace only one tire, the replacement should be the same model, size and tread pattern as the others. A different brand or model tire will have even greater differences in traction and number of revolutions per mile, and it's likely to wear at a different rate. That means it could conceivably wear out faster than the others, even if it starts out with more tread depth.

Since you're in Florida where it rarely gets cold, you can go with Summer tires.
