For another twenty two bucks a tire, go with the RT-43.
I'd want my lady on something decent, although I'd be tempted to fish the bottom if I were going to drive the car myself.
If you poke around online, you can find cheaper thriteen inchers and you can always check out the local yards and CL.
Good online sites for obsolete sizes and models are treaddepot and tires-easy. If you could find Cooper Trendsetters in your size, they'll be dirt cheap and are decent tires. Our old '97 Accord came on a new set of Trendsetter SEs, and they were okay under all conditions and lasted 68K.
The winter beater Focus I bought last September came on nearly new Primewells and they aren't bad either.
A yard might be your best deal, but be sure to learn how to decipher the date codes and avoid anything more than seven years old.
Around here, yards will sell you a tire mounted and balanced for twenty-twenty five dollars, while anything bought from a private party on CL will mean that you pay for mounting and balancing.
If my wife were going to be using the car, though, I'd bite the bullet and pony up for the Generals.
If you end up using the car over the next winter, the Generals are also reportedly pretty good in the snow.
I can tell you from personal experience that the Primewells are like AS tires of a few generations back, but they'll work in snow if you work with them and if you're an experienced winter driver. Living in PA, you and your lady probably both are.
If this old 'rolla is really well cared for, you might find it useful for at least a couple of years, so it might pay you to put decent tires on it now.
There are better places to put your money than a car, after all.
