Is my suspension bad?

[Mark]

I bought a second tire to replace the left rear just in case that was the case, but haven't gotten around to getting it done yet. Would the off-kilter feeling still be noticeable if I had under 5,000 miles on my other tires?

I would try to match tire pairs on each axle as close as possible. I used up a pair of my original factory Dunlops along with a pair of cheaper Federal SS657 tires. I currently have a pair of Kumho Solus TA31 tires on my front axle and Nexen N'Priz AH5 on my rear axle. I haven't had issues using tires in pairs in this way, & I have been doing things this way since my former 1990 Ford Festiva (over 30 years).

I would try the same tires/brands on the same axle & see if that helps. I realize the one tire has some miles on it already.

My AWD vehicles have been a different story. I make sure all 4 tires match, & they are rotated on a regular basis.

The easiest and cheapest thing possible, would be to check the air pressure. If you travel on bad roads, keep the pressure not lower than 40psi.
