Can I add a question to this? I just bought a 1984 Toyota dolphin. All 6 tires are flat. The mounted one's are 195/70 r14. I have a chance to buy 4 hankook vantra Ra18 205/75 r/14 Brand new for half price. Are they to big for the rear? I've also been thinking of single in the rear. Is that possible and or what tires will handle it.
