I've run the Barum tire (185/60R14) on my 1993 SSGT (Suzuki Swift GT) and they perform very well. No experience with Barum tire fitted for XFire.

But I would suggest you try checking on a set of Vredestein Ultrac Sessantas for the XFire. I got a really great price for set of Vredestein Sportrac3 (195/45R15) for my 1993 SSGT back in 2008 from a dealer in Florida and he shipped me the tires overnight. Hard to find size for the 1993 SSGT and the tires perform better than anything I've used before. Based on the SSGT handling, I'm convinced the tire for the XFire will also more than meet my expectations. (Note: I attached a brochure with the XFire tires highlighted.)

Here's their contact info:

Hi-Performance Designs, Inc.

Fax: 813.707.9893

I also attached brochures for Hankook & Cooper tires that are available for the XFire. There's also another Hankook tire (V12 Evo / K110) that fits and apparently I've already posted that brochure somewhere else according to the Forum, so I couldn't post it here.

There are some bargains out there, but you'll have to look. And I fully understand your position of being able to deal with a local supplier where all of this web searching is eliminated and you're back on the road with minimum hassle. Probably will feel the same way when it comes time for me to get a set for my 07 Coupe.
