Lets talk about wide 20s
This post pertains to fitment on a 73-87, but I will use some 67-72s for comparison too. I want to explore the options of wide rear tires without massive modifications. PLEASE do not talk about tubbing for 24s here.
I have been considering new wheels and tires for a long time, and the itch has struck again. If I dont have another cash emergency that drains my fun money, I am back on a mission to find a fresh tire/wheel combo. After considering the many variables and what it takes to make 22's fit to my satisfaction, I realize I will have to mod the inner fenders in front to make them fit properly and still run fender liners. Combine that with the fact that they dont make a wide 22 for the rear, and I have just about given up on running 22's. I do NOT want to run staggered wheel sizes. Lets take a look at whats available for the rear without going to a 30 series tire. Sorry gang, but I like some meat on the sidewall. What I have been able to ascertain is the 335/35/20 would be an ideal size, but its extremely limited availability and price almost rule it out. That leaves the 315/35/20 with decent availability, but not much wider than the 295/40/20 I am currently running. I cant believe that narrows the options down to an over priced 335/35/20 or the Mickey Thompson 295/15/20. The M/T tire is available at a fair price, but currently M/T does not offer a matching 20" front tire. Whos got some wide 20s, and what did you do to make them fit? Narrowed axle? Stretched tubs? Trimmed lip? Pics are golden too.

Re: Lets talk about wide 20s
Ken,... I assume you are talking about running a 12" wide wheel on the back?
My opinion,... only a 335 looks right on a 12. 305's and 315's look stretched to me. Personally I would run a 20x10 or 22x10 with a small backspacing and narrow the rearend. That get's you a bigger lip on the back wheel, but doesn't require any wheel tub mods. (I would run a 3.5"-4" BS on a 10" wheel) It will all depend on how much you can narrow the rearend without getting into your RideTech 4-link. Then you can run a 305 tire if you want a meatier look. I like the tire sizes you are running now. My Belair has a 20x10 (with a 4.25" BS) Just right, in my opinion. Not too much, not too little,...

Re: Lets talk about wide 20s
I'm glad you replied Keith. It seems like every search I did looking for options led back to a few posts that you had commented in with great info. I am looking at a couple of different style wheels that are available in a 20x10, 20x10.5 or 20x12 . I know a 20x12 will work with stock leafs, so I will assume it will work with the RideTech 4 link.
I like the 295/40/20 that I have now, but i would LOVE some extra meat in the rear. I'm not looking for the old Pro Street style, just want some wide rubber under it. It really looks like the simplest option is the M/T 29/15/20 out back, and a General G-max 245 40 20 up front. Thats what classicchev has on his Blazer and the tread matches pretty close.

Re: Lets talk about wide 20s
I think that combo is what you need brother ( MT/General G-max). DA the ID/brand tag off the sidewall & roll.

Re: Lets talk about wide 20s
Ken,... Mickey Thompson recommends a 13"-14" rim width. Is that the plan?

The bed floor is the limiting factor here. I know a wider stock tub wouldn't look bad, but I am trying to avoid that option. I still have not given up on the 335/35/20 option either.

Re: Lets talk about wide 20s
I know you said no small tires but figured I'd share some piks of mine since I was working on
it all day getting it ready for its c notch and qa1 coilovers on mine it's a 20x12 with 345/25/20 toyos on it i personally think for a 12 in. Wide wheel to look good you need at least a 325 or wider tire cause I believe a 315 looks streched but here's some piks so you can get an idea of how wide they are good luck on your pick |

Re: Lets talk about wide 20s
I spent a lot more time searching the Web last night. It seems that they are no longer making the 335/35/20s. The 315/35/20 specs out to be shorter then the 295/40/20 for minimal gain in width. That leaves me with two options viable for my application.
I can go 295/40/20 on a 20x10 or the M/T 29/15/20 on a 20x12. I looked again at my clearance and I might have issues with the bag mounts 😕 . They actually make a couple of the styles in a 20x10.5 I talked with Scoti and he feels the 295 would not look stretched. I need to find some good side views of 295 on 10s to feel comfortable that the 10.5 will work. 😩

Re: Lets talk about wide 20s
I'm not set on anything low69chevy, I am simply exploring options. I "want" a wide tire out back. However, I must decide how badly I want it and what I am willing to do to get it. Modding the bed floor and running a wider tub is not major. Redesigning the bag mounts is a whole different deal. I am capable, just not sure if I am willing.

Re: Lets talk about wide 20s
I'm setting my 77 up to run a 20x10 with a 315/30-20 on all 4 corners. I'll post some pictures when I get home tonight.

315's need 11" wheels to have squared (non- pinched) sidewalls. 315mm on 11" wheels (5.5"bs) should work (for N2TRUX) if the slightly shorter rear height is acceptable. That stuffs the well as much as possible w/o having to make other changes.

Re: Lets talk about wide 20s
Thats a pretty general assumption, as you can get tires in the same size and quite significantly different sizes.. The Pirelli P-zeros im running can be had in 3 different section and tread widths for the same size.

He & I have discussed this more than once. He wants/needs overall height, sidewall height, & symmetry (balance) w/the front set-up. Hard to find that balance, especially in matching tread.

Re: Lets talk about wide 20s
I miss read your last post.. my bad.. i went back through this post and seen where he was going.. i read through it too fast the first time.
With the 315's you could do a 40 series on a 20 and be at about 29.9 ish.. and a 35 series drops down to about 28.7.. that mathmatical, you would need to actually measure a set to get close his size.

LoL.... Sometimes you never know where your answer can come from. N2TRUX & N2Billet call me the "numbers" guy but nobody knows everything.

Re: Lets talk about wide 20s
He never said he wanted more lip, he wanted a wider tire. Getting a 10" wheel with minimum backspacing for more lip doesnt solve his want for more tire!
Im planning on 20x15s in the rear of a square, the closest match to the MTs I have found is the Toyo Proxes STII. Planning on running a 255/40/20 up front and the 29x18.00R20 in the rear. The two side by side are really similar take a look at them when you got a chance.

While I agree that the Proxy STII does look similiar to the M/T tread, I feel the General G Max looks much closer.

Re: Lets talk about wide 20s
Trying to post from my phone so bear with me. For discussion purposes, here's a absolutely beautiful example of what a 295/40/20 looks like on a 20x10 wheel. This looks excellent this, but I want a more width. I feel the sidewall height is spot on, with proper proportions.
