tire size ?


Not sure if it´s the right board.

My Question :
would 235-70-15 or 235-75-15 fit on a 58 Pathfinder?confused
without rubbing on the fenders or something else ?
i dont like the bias with 14 inch.
they look too tiny and handles bad, but i would like to keep the old look with white walls.
Thanks

Patty 58

It depends on the rim and rim offset.. I think if you use a stock rim, 15x6 like a S10 they should fit... The P225/75R-15 is probably the best fit.. Carl

What size is your original tire?  Should be listed in your owner's manual if you are not sure.  235/75-15 is a large tire, equivalent to J78 x 15, which only came originally on large station wagons in the early 70s.

I have 235/75-15's on my 60(wagon) and they fit OK, even with it lowered. I used 15" rims off a '79 Impala. If you have manual steering, it makes it a little harder to turn, but I have no problems with rubbing.

Perfect!  thanks!   Did the 79 impala wheels, measure 15x6 or 15x7?    A lot of people, measure a rim, from the very edge to the other edge.. Most 15x7 wheels, for eg. are 8 inches edge to edge..    wheels are correct, measured at the bead seat to beat seat.  A 79 impala would have 15 x6 wheels, and 79 Impala's with F41 suspension would be 15x7's   which are great to get ,and fit on Beumont's, Acadian's, Ventura'S, FOR THE POVERTY wheel look..

OOPS, Never measured them, probably 15x6, it was a plain 4door sedan, nothing fancy about it.  Just wanted bigger rims and tires to fill the wheelwells better, the "wide track" Pontiacs of the US never applied to the Chevy based Canadian cars. There had to be about a foot of clearance between the wheelwell and the original 14"

I am probably in a minorty here because I don't like messing with over sized or undersized tires etc that significantly differ from original. I'm with Astro Jet, give us you original size and we can make a recommendation. I like to keep the overall height the same as the original no matter how wide or what wheel size you go with.

Those 235-75-15" are practically a pick up truck tire.

i think my original tires are  8,00x14 bias
should be around 215-70-14 or 205-75-14.
anyhow , i like to get rid of the bias plies, because they handels so bad
But it must be a wide white wall again for the factory look.

Thanks for the opinions

Coker recommends 225 75 14 for your car, have a look:

Wide White Walls - Click Here

Those 235 75 15's are 30" in diameter and the recommended ones above are 27.6". That's about one and a half inches taller. They would probably fit but you'd be riding higher and that sort of difference would affect your speedometer.

I checked the Coker Chart and 215 75 15 are 27.6 diameter so that would be the same height as originals.

       The one and a half inches taller, is really only 3/4 of a inch higher at the road...then of course ,you can get into "loaded radius", which is the amount the tire squats, from the centre of the wheel to the road.. If you are using radial tires, compared to old bias tires, the amount of squat (or deflection) is more, allowing for use of a supposely taller tire  C2

        Yes Patty, I think a P225/75R-15 0R P235  would fit on a 15X6 rim..  SIXTYWAGON   says he has no problem wiht them....

But the circumference isn't going to change, regardless if the tire does squat somewhat.  Going from a 215 to a 235 tire will effectively lower your axle ratio thus decreasing performance and throw your speedometer off, although you should get slightly better fuel economy.
