can anyone tell me whats the largest size tire they are running or can run with 14x6 magnum wheels. The old tires Im taking off are 235/60/14s which are big. Im surprised they were on the car because I was told a tire that wide isnt safe on a 6 inch rim. Whats the biggest tire I can use with no rubbing in the 70s series and the 60 series. Any info is appreciated.

What year car, and what if any mods have been made to the suspension? Both bits of info are needed to make any kind of intelegent response.

The widest tire that is recommended to put on a rim is where the rim width is 80% of the the tread width. So, for a 6" wide rim, the max tread width should be about 7.5". Any wider, the sidewalls will begin to loose strength inducing less strength to remain "standing" when side or lateral loads are applied. The wider you go past this, the less strength you have.

The most narrow tire should have a rim width of 90% of the tread width. For the 6" rim, this would be about 6.75".

Now befor anybody has a cow or ?, please remember you can go wider or smaller, but this is the recommendation from most tire manufactureres with regards to maximum handling capabilities for a tire. 2nd but......always check with the tire manufacturer whose brand you are about to buy for the recommended tire size versus rim, you would be surprised at the differences between mfg's with the exact same tire size versus their design specs!

I looked on this BF Goodrich tire chart and it looks like a 215-60 or 70 would be the widest to go, possibly even a 225-70.

I'm running 235/60R/14's on the rear of my car (14x6 styled steel rim). I had Goodyear install them they told me (when I ordered the tires) that the 235 size is the widest that they'd recommend with a 6 inch rim. Any wider you run the risk of breaking the bead during hard cornering (at least that's what they said ) I've run these tires for years and have never had a problem.
