Shagy Posted January 3, 2012 Report Share Posted January 3, 2012 my 71 has some B78 13st's on it.... I believe that converts to a 175/80/13..is that correct? All I can find in that size are trailer tires. I just need some cheap cheap tires right now that hold air. But eventually I'm going to get the same size in a decent tire... help Quote Link to comment
datsunaholic Posted January 3, 2012 Report Share Posted January 3, 2012 Closest match is what they used in later years- 165-80R13. That's what I have on my Wagon. Quote Link to comment
Shagy Posted January 4, 2012 Author Report Share Posted January 4, 2012 thats a hard tire size to find. found out one of the tires is a 175/80/13. I just need some rollers right now.. Quote Link to comment
MikeRL411 Posted January 4, 2012 Report Share Posted January 4, 2012 I use P155R13 Remington Maxxums from Fosters Tire shop on Rosecrans near the 405. They have the advantage of being so close to the original "86 series" tube type in diameter wlth wider road patch that handling and speedometer calibration are not adversely affected. Don't know what part of SoCal you're in, but I have been using Fosters since 1972. Quote Link to comment
ggzilla Posted January 4, 2012 Report Share Posted January 4, 2012 B78 was not the stock size 510 tire. It was 6.00 x 13", wasn't it? The stock optional radial was SR13, which is close to 78-series, now sold as 80-series. Quote Link to comment
Shagy Posted January 4, 2012 Author Report Share Posted January 4, 2012 I'll have to go to the shop tonight and look @ the tires again. I really want to roll it out on some OEM stuff for a while before putting some 280zx turbo wheels on it...but if is too hard I'm just gonna say screw it and get some 175/80's or something like that. but I"m hoping to find some used tires right now. I have one tire that goes flat in a couple hours. need to be able to push this around the shop. Quote Link to comment
datsunaholic Posted January 4, 2012 Report Share Posted January 4, 2012 They don't have used tire stores in SoCal? I was up at one here in WA, they had probably 10 sets worth of 13s. Really, I wouldn't sit it on OEM tires. They're 40 years old. Just get 4 matched or 2 pairs of used 13s in the same size. 155, 165, 175, they all fit the stock original wheels. 185 probably too, but maybe a bit wide. I wouldn't even try finding a B78 tire- it's a bias-ply tire only made for trailers nowadays. Quote Link to comment
Shagy Posted January 4, 2012 Author Report Share Posted January 4, 2012 they do, I just have not had time to go talk to any yet. I did notice that the tires on it are now trailer tires..... this car has sat since 79 =) its OG Quote Link to comment
ggzilla Posted January 5, 2012 Report Share Posted January 5, 2012 Bias-ply tires were never OG ... radials were a Datsun option in 1971, that's what the coolest guys chose. Quote Link to comment
Shagy Posted January 5, 2012 Author Report Share Posted January 5, 2012 hmm. I guess I'll just stick with trying to find the 165-80R13's or a 175/80r13. Quote Link to comment
