mixing tires question
front stock size runflats (GY) and rear stock size non runflats (wideovals) what could I expect....safety, handling, highway driving, town driving......this is not a permanent thing just trying to use up some good front tires before buying new firestone ovals to match rears. thanks.

When I bought my tires, I asked the same question. The tire experts told me that mixing the tires would cause the non run-flat tire to run hotter. Not sure why, but that is what they said.

I have had the GoodYear RunCraps on the front and Michelin PS2's on the rear for about 10 months and no issues. When the Run Craps get a little more worn I'll put the PS2's on the front as well. Didn't have the $$$ for all 4 Michelins when I put them on the rear plus the RunCraps still had meat left on them............ As always YMMV
I don't like to mix either but wanted to be sure no major safety issues etc.

The stock runflats have a very stiff sidewall. Wideovals non RF are much softer and more flexible
You'd have a stiffer front end and a softer rear end which on a high performance rear wheel drive car I'd say isn't a good idea.
I doubt its a safety issue if you run matched pairs at highway speeds. I'm sure AH will compensate in all but the hardest manoeuvering. However, it has to degrade the handling somewhat.
I wouldn't do it personally. JMHO
