They will fit on 4.5bs too, which is a standard bs on most 10"rims. Then you just narrow the rear to fit them. After that any 15x10 off the shelf 4.5bs will fit. Narrowing the rear is not a big ticket item. And IMO the deep-dish wheels just look so much more at home on our classics; subjective I know. Plus, almost any smaller-than-10 wheel will instantly fit.
The thing is 325s should really be on 12s, so you can run decent tire-pressure. On 10s you will be down at around 20/22psi to get them to run flat on the road. Even my 295/50s have to run at 24psi on 10s to get decent treadwear outta them. And yes, my 295s rollover onto the sidewalls on every turn, sometimes I see the scuffmarks over an inch high. It will be worse at 20/22 with 325s
And the real insult for me was that my car was not perceptibly quicker with 295/50s than with 275/60s. And those I could run at 28psi, with little to no roll-over. I coulda saved some money and just got me some Caltracks.Or ladderbars. Or SS springs, or something,lol.
What I really need is 285/57-15s,on 10s,lol.
But I gotta admit 325/50s look really good under there.
Here's a bit of trivia;
A 325 is only a 325 on the designated checking rim....... which is 70% of the branded size. So in this case 70% of 325 works out to a 9" rim. If you mount it on a 10" rim, the section width will grow about 50% of the increase; in this case about a half inch or 13mm. So now it's a 338. But this also affects the profile spec, cuz the height does not change. So in this case the profile becomes 52.83%. so that gets you a 338/52.83-15. But tire companys will round this to 335/55-15. And when they do that, the checking rim will be just 9.23;which rounds right back down to a 9incher,lol
The point is that the 325/50-15 itself may be a victim of rounding. It might actually be a 320.1/51-15 mounted on a 9" checking rim.
So what says you
Well the 295 might also be a victim of rounding. The checking rim is an 8. When you install it on a 10 it will grow in section about 1" or 25mm. If the 295 was a rounded down number from 299.9 then it will now be a 324.9 on the 10" rim. Of course the profile will now be 47% leaving you with, dare I say it, a 325/45-15 after rounding.
Of course this does not affect the part that counts, the part that touches the road. And a 325 will always be wider.........than a 295.
The point is this; if you don't actually need the extra treadwidth, then you can make a 295 look almost like a 325
Jus saying......
