Anyone know if I can fit 205/65/15 tires on my stock rims without rubbing?

Current tires and door jam both read 195/60/15 as normal tire size.

To me; it looks like the front would rub. I don't want them to rub even on bumpy roads, etc, no rub at all!

Suspension is all stock. If you're curious why I want to do this; I want to increase the payload capacity. I've already looked at all the size differential calculators, I know about the recommended 3% change limit and this is about 5%. My alternate tire size would be 205/60/15, which I don't think would rub, but that wouldn't add as much payload capacity.

Thanks!

Don't know. That tire has a lot bigger circumference than stock. I put on 9-5 215/55-16 tires for a bit, and they rubbed at full lock. I did not load the car, and didn't drive it like that a lot. And those tires are a bit smaller in diameter than what you're proposing (albeit wider).

Stock 195/60-15 tires at inflation for "full load" will already carry the maximum load allowed by Saab, and that's less than the maximum load the tires could possibly carry (at an even higher pressure). A tire with an 88 load rating is rated for more than 1200 lbs. Your car is not limited by the carrying capacity of the tires.

The stock tires are good for four people and a bunch of cargo; something like 800lbs total between people and cargo. The convertible chassis isn't as stiff as the sedan or coupe chassis to begin with.

I would almost guarantee that you would get all sorts of rubbing with any of your proposed oversized tires if you load up the car with half a ton of stuff. The suspension is not really designed for that kind of load.

You could have summed that up into "i don't know at all" or just stfu to begin with. lol. Always bunch of jokers want to chime in that haven't even got the car to begin with. Although you did help to convince me I don't need too much more load capacity on the tires. 205/60/15 should do it.

Well, with your jovial and appreciative attitude, you're sure to get lots of help around here in the future.

EdT is right and gave you proper advice: You're not going to gain any payload capacity. If you're pushing it that far, you will just bottom out the springs on every bump. Meanwhile your car is going to handle poorly and sway - not just from the overload, but from adding .75" of sidewall to the lowest performing tire/wheel combination Saab offered. No one here would recommend doing what you plan to do, even if it doesn't rub.

Enjoy the ride.

Exactly. The car was already set up for maximum payload from the factory. Saab knows how strong the car is, and how much it can carry, that's why they picked the load requirement that they did! If the car could haul more, they would require more than an 88 load rating. Going above it won't allow the car to haul more, and that is a fact.

But you know, I only tell this to people every day where I work, but have fun ruining your car by "magically improving it's payload rating by installing the wrong tires because that magically makes the cars frame stronger".

nobody asked for advice. a question was asked, a specific response was expected, but internet supertards always have to chime in. They have no idea what mods I have and have planned otherwise. WAAAAAY too much speculation on my setup and also speculation on my plans. Also, f*ck Saab and their engineers and whatever they think the frame is good for. If the question isn't asked, don't answer. I would go as far as to say the entire thread is hijacked and the user should be banned for hijacking it with useless info. Nobody gains anything from this. If someone wanted to know stock specs they can look in their door jam, I don't need your crap and nobody asked if you or anyone else "thinks" its a good idea. I wanted to know if YOU "KNOW" if the frakking tire size would rub, JTFC. Innovate, create, think outside the box, be an American for your moms sake.
Goodbye.
