Hey All,

I've got an old set of GSL-SE rims, want to keep my current ones in good shape.

What's the narrowest tire I can fit on those rims? Can I fit 185/70R14s?

Thanks,

Yes, I believe that's the stock size, but don't quote me on that

S and GS came with 165's
GSL came with 185's
GSL-SE came with 205's

Why would you want to use narrow tires?

Yeah...I was thinking the same.

Maybe gonna make an SE loooowwwwrider

White84SE

No... I'm almost willing to lay money he wants narrower tires for snow driving.. which would explain wanting to use an old set of rims... in answer to the question, yes, you can use 185/70's.. my old '84 SE had that size on when I bought it..

I think the winter thing is right. I just went to order 185/65 Icetrak tires for my winter car ( a Subaru Legacy). I got these just in case my winter car craps out and I am forced to drive the Rx-7. I'll just move the tires from the clunker to my RX.

Yeah, sorry I should have mentioned that earlier.

I was looking for them for the winter.

I was mainly worried that because the stock tire was 205/60R14, that 185s would be too narrow for the rim, but I guess there's enough tolerance.

Thanks!

Question: Why would you want narrower tires for use in the snow?

Manntis

Narrower tires cut through the snow to reach pavement, whereas wide tires disburse the vehicle weight over a greater surface area and cause the tire to ride on top of the snow... this allows the snow to act as a lubricant, making traction (if you can call it that) slippery

Cool. Thanks Manntis.

good explaintion ther Manntis... i was going to say the same thing,, plus I think u get better fuel milage.. don't u?

Forseti

I would also think that narrower tires would reduce friction when driving on new snow (less area) (less prone to getting stuck), and drag forces in general.

However, I may have to get some adjustables and crank it up a bit so I don't end up snowplowing through with my bumper in a heavy snowfall.

I'm not sure how much it's gonna add to fuel mileage, but I'll certainly find out this winter.

Thanks,

If you're getting bumper-height drifts in TO, somethings wrong. On the prairies they keep the streets reasonably plowed and the tax base is far, far smaller...
