90S vs. 90H tires

Hi all,

I've got a '96 Camry (174k miles). The tires are pretty worn (via the quarter/Washington's head method). The struts (shocks?) are also shot... BUT, since we're not sure how much longer we're going to keep the car, we're hesitant to spend $1000 to upgrade the shocks. (Car handles just fine, if it rides a bit rough, and the shocks aren't leaking.) I sure don't have the skills to change the shocks myself.

The '96 Camry uses the P195 70R14 90H tires.

My wife has a '99 Camry with good tires, P195 70 R14 90S.

We're sure we want to keep the '99 (< 98k miles).

I'm thinking of putting the good tires from the 99 on the 96, putting the worn tires from the 96 on the 99, and taking the 99 to Costco for

Is this a bad idea?

Is it ok to mix 90S from the '99 to the 96, where the manual specs

Thanks,

Michael
