Tire size reco

[Omaha Bill]

Finishing the restoration on my "70 Challenger RT/SE that has 5.5" Road wheels. Need to decide on what size of T/A radial to buy. Conversion chart says F70 converts to P215. Thoughts on what size fill wheel wells looks best? Maybe 215 front and 225 rears?

According to the chart the F70-14 equivalent is 200/70-14(I think 205/70-14 is more realistic to find)

I've always gone wider, 225/70-14 works well. Last time I went 235/60-14 & they look/drive great but are technically to wide for the rim causing the middle to bulge a bit (that's on my stock 5.5" wide Road Wheels
I see Radial T/A's listed in 225/60-14, may be good option for you.http://www.tirerack.com/tires/TireSearchResults.jsp?customSizeSearch=&width=225%2F&ratio=60&diameter=14
Here's a chart that shows the relative differences in tire size & diameter , I entered 205/70-14 to compare.

I've got 225's 70 series, 14" on the front of my car. There is a little bulge, but no problems.
