20" Rims 35" Rubber

[7schulz]

Does anyone run 20" rims with 35" rubber? I’ve had 35's on my last cruiser and have a stock one now but am looking for another one that I'm going to build for my purpose of 95% dd on road but able to go off when I feel like it b.c in the Midwest I have to go to a special park to play. 3 1/2" lift with 20's and 35's, 1" wheel spacer, a SC and mostly stock besides that. It will be an LX450 so I was hoping to keep Lexus rims like the LX570 rims or maybe the 18" rims on the LX470. Do the Tundra’s have a 20" option. Wheel spacers should be able to go from 6 to 5 lugs right?

If you off road at all 20 inch rims will suck and will not work very well especially if you air down
you will srceww up the tires and the rims

I've wheeled a ram with stock 20's and they were only 33's not worried about the 35's

What he said.

Not enough sidewall to get any sort of decent flex out of it. And the large rim will be more likely to get into harms way than a 16"-18" rim.

Why do you want to use a 20" rim when there are so many good choices in the 16"-18" flavors?

I like the looks of it.

Count your lugs. You have 6 per wheel. LX570s have 5.

You missed the last line in his original post.

Works for anything besides rock crawling. Then, like everyone already said, its a bit shy on sidewall flex. If you run 20's Id do a 37 minimum if you plan on hitting the rocks.

20s on a LandCruiser? Say it ain't so......

 

[yOHda]

the rule is 20 over. so for a 20" rim you want, at a minimum, a 40" tire.

20s have there place though...the new 42" BFG Krawler sticky only comes for a 20" rim i think.

I would totally rock some nice 20" black or anthracite rims and 35" MTRs or something similar on the rig. Its not like I am allowed to wheel the S^&t out of it anyway... And would still work well for some light duty dirty fun.

Now i got to see this, i guess you will be unique if anything.

 

[yOHda]

it honestly doesnt look bad at all.

Great. Thanks for putting that in my head yOHda.

They only look okay because thats the most desirable wheel and tyre combo on earth.

Walker evens and MTRs, drool.

If you go wider,would you have to air down?




They make 6 to 5 lug adapters.

Something to keep in mind besides a lack of sidewall height is the added unsprung weight that the 20's add.

Not only will your suspension be working harder on the street making your ride over the potholes suck, that added weight will compress your already reduced sidewall even faster when offroad obstacles are encountered.

Most vehicles I've driven with 20's suffered in the ride department due to the added unsprung weight.

I'd be willing to bet a 20" alloy wheel with a 35" tire combo is lighter than a 16"/35".

I've seen this thread before, it goes something like this.

"what do you think about this idea?"

It's a bad idea.

"no it's not."

Yes it is.

"I'm going to do it anyway, thanks for your input."

Depending on the tire/rim combo, what he said.

And weight isn't an issue. Lots of 80's overseas running steel rims and heavy tires without issue.

The reason 20" wheels and 35" tires suck is that the side wall is so short, they're typically made of a heavier side wall construction. Seen more than one tire that adds a ply when you get to that ratio. E.G.: 2 ply for 16/17/18 inch rim and 35 inch tire, 3 ply for 20 inch rim and 35 inch tire.

Less side wall means less room for the tire to flex and compress, which means more of the impacts from the road are transmitted to the vehicle.

You are right that a 20 inch rim and 35 inch wheel will have a worse ride than a 16 inch rim and a 35 inch tire, but it has nothing to do with weight and everything to do with the short sidewall and construction of the tire.


FWIW I'm running steel H1 rims with 37" military tires which are far heavier than the alloy 16's and 35" tire I was running previously. The ride is actually improved partially because I run at a slightly lower PSI (30 vs 35), but the bulk of the improvement comes from the significantly larger sidewall allowing the tire more room to flex. (And this despite a much heavier construction, 4 ply vs 2 ply.)
