Tire use question- I saw an add for 90% Michelin #15.5 R20 tires. Can I use them in front axle with my A2 5 ton with worn to 60% 14.00r20 super single rears? the listed dia is 47" for these and a bit more for new # 14 r20 tires. I don't lock my front axle unless offroad or snow covered roads. The # 15.5 tires seam newer than the surplus 14 r20 for sale and cheaper too! I can't afford to change all 6 or 7 tires now. Will these slightly wider tires clear my steering OK, and what are they now originally installed on? I have the stock 2 piece rims. Thanks for any info!!
