Has anyone had problems installing 275/35/18's on a Dart or Valiant? I am installing offset shackles on my car and was hoping I could stuff those on as I need new tires anyway. I know there's the hump on the rear wheel wells. Does that usually interfere under compression with wide tires?

I also noticed that the center hub on my Dr Diff axles is larger than the centerbore of my current wheels so my 1/4" spacers are required for now unless I machine them out or buy a new set of wheels (which I'm thinking about). Does anyone know that center hub diameter?

Anything I should be worried about in the front? I already have larger T-bars and have raised the car just a tad to avoid machining tires as I was doing before.

I'm currently running a 255/40/18 all the way around. 18x9" with +32mm up front and +17mm in the rear with the offset shackles. I was hoping to get a square setup with both wheels and tires for the next iteration.

Samy what tire are you thinking about getting?
Since every 275/35-18 tire brand has different widths it is important to figure into the equation. For example a BFG Rival S in that size can fit a 9"-11" wheel. I would run at least a 10" wide wheel to get more tire on the road.

I was planning on running Bridgestone RE-71R's which is in about the same range of 9-11" wheels. If I was going to a new wheel, my math says that an 18x9.5" Enkei PF01 +35mm offset should be just around ballpark of what I need.

RE-71R's are a great tire! I think they are a bit on the narrow side as well. I have a set of 255's and they are narrower than my previous Yokohama AD08's. The PF01 is also a strong wheel and glad you are able to find the size you need. PF01's should be around $300 bucks each and lots of people use them on the track!

I mean, once the job is done and the rear end is centered, I just need to measure everything up to verify it will fit. Where are you finding them for $300? Silver or Black? laugh

I paid $320 each for two PF01's about 3 years ago, they were 10.5's whoops I didn't figure that they would be more expensive. I love black wheels but keep in mind it is more difficult to find cracks when they develop. I still vote black though!

I found them here for $353

My guess is that the Dr Diff hubs are the correct size for Mopars, 2.81".

Good to know. If anything, I could show Summit or whoever the price and ask them to price match. I like blacks, but I'm just wondering how an all black wheel would look on my car.

A guy on FABO measured it for me. The Dr Diff bbp axles measure 2.795" (~71mm). The stock bbp axles measure 2.825" (~72mm). So, I should be good with Enkei's if I choose to go with them.

I have a 275/35/18 square setup on my 72 Dart swinger...im running 18×9.5 Enkei NT03+M wheels with Hankook Ventus R-S4 tires. The rears are a 38 offset and fit perfectly with the Explorer 8.8" @ 59.5" wide and the Dr. Diff offset kit. The fronts are a 27 offset and clear everything and no rubbing the frame.

My aluminum brake rotor hats are 0.250" thick front and rear so thats factored into it too. Without the hats on the tires would just be a hair from rubbing the frame in front and the leaves in the rear.

My next tires will be 285s as my offsets are bang on so i coulda gone bigger but i was playing it safe for the first ones. Also my tires dont measure out as wide as the spec sheet said they were either.

Not sure how you squeezed 275's in the back of a stock 72 Swinger. I could just get 245's in, rolled fender lip, stock spring location. Had maybe 3/4" clearance ins'de and out.

That would just barely rub the leafs on hard turns.

Dr Diff says 1/2" more, which is maybe 13 mm. I guess if I was running 35 profiles instead of 60's and left 1/4" inside and out for clearance it could be done. Is you fender lip rolled or cut?

I had 275s on n the back of my 69 Valiant with the offset Shackel kit ... so they should fit a 72 Dart as well.
JRC are you driving this beast around our fine Winnipeg streets yet?

That sounds comforting to know. It might be awhile before I can buy new wheels and tires. I just bought a new car.

If i had a way to upload some pics i would...on my rears i have about 5/16" from the tires to the leaves. They just squeezed on without trimming the lips but it was like 1/8", so just trimmed the lip back about a 1/4". The fact that these are low profile tires with a larger rim is why it fits along with the 1/2" leaf offset. I had 245s on 14s and they had cuts on the sidewalls from rubbing.

Also have hotchkis sway bars to help with roll along with 1.12" bars and 2 leaves added to my hotchkis leaf packs. So the wheels arent moving around nearly as much as the old 245 tire days! I have about 5/16" clearance everywhere...never trimmed front fenders or pushed anything in or out either. But have some good static camber and 200TW tires too.

Car is in shop being finished up with fuel cell and sub frame connectors, aluminum radiator and electric fans. Be back on the streets next summer. I have a 4mth old boy thats slowed my progress down this year! lol

Sounds pretty tight, but the low profiles help. I was running a 3/4" rear sway bar as well, but the taller sidewalls let the tire flex enough to rub.

This wasn't a dedicated track car and I really do not like the feeling of a low profile tire on the street.
