Are dual rear wheels going to be better than Singles? We have no restrictions on this right now and I was thinking of getting a set of dualie wheels to run on the rear. Is the added weight and rotating mass worth it?

If you have the HP and the driveline to handle it then it is worth it.

If that were the case you wouldn't see all of the non cut tire guys running duals. Sometimes you may not want the extra bite, especially if you have a manual, and need to blow the tires off to stay on the charger. This has been debated before.
 
So the dual rear wheels are worth it? like has anyone done single rear wheel hooks and then done dual rear wheel hooks and done a good deal better or anything like that?
 
Like Dan said. If you have the hp to keep them turning and turning hard. Without a doubt they are better. You will have to beef up the driveline though. If you are 600 hp and under. I see no reason at all for them. I guess before I say that. What class do you pull?
 
I am curious

It makes sense that the more sq inches of rubber on the ground, the less pressure/weight per sq inch there is to hold the tire on the ground because the weight is distributed across a larger area.

I can tell you we had much better traction on a 12:50 tire than we did on a 15:50 tire and i am assuming thats the reason - more weight per sq inch of tire contact

We actually found it easier to turn the larger tire

or is this a fine line of some sort?
 
Ken im thinking that your bad luck with the wide tires might be a result of the different tread patterns between the tires you were running. Also maybe the poor tracks we have up here dont have the bite to hook up a wider tire? If you look at most of the guys running duals down south it seems to be on good clay tracks most of the time i think.
 
um that was the one try where we ran 12:50 front and 15:50 rear, most of the hooks used all 4 15:50s the nwe made three runs with the 12:50s and did much better

but u may be right we dont have many good clay tracks

If the dirt could hold every bit of power your tire would hold, then that might be the case. The dirt can't, so every little extra inch helps.
 
its for a 3.0 truck, just kinda curious to see the results everyone else is getting with or without
 
So for any given weight class, the widest tire or biggest tire contact patch will get the most traction and you guys are just adding more tires to increase the total tire patch?
 
What i dont get is, theres been gas truck classes that have been pulling for years and years with plenty of power to run DRW and they havent used them. But diesel guys (3.0) almost all do except for a few which seem to do just as well with singles. I mean is there a real reason for all this or is it mostly just a (sheep) thing? Has there been people who have pulled on the same track close to the same time(similar track conditions) with singles then with duals and got better or worse results?
 
Ya i'm just looking for results on both as in how much better they'd do with the dual rear wheels than singles, idk i figured id just pick you guys brains about it, cause it just seems a good amount do it just cause others do it (sheep)
 
I think I'd rather run a wider offset in the front and a slightly inset tire in the rear. 1.) Your cutting fresh tracks with each tire 2.) Your not throwing loose dirt in the rear tires path. Thats how most gassers are setup, pro mods also. I'm not a big fan of duals myself, but 4 a very loose track I'd consider it.
 
This is a crazy idea but here goes, Any one ever ran duals on the front end, single on the Rear?
 
Unless your pulling in sand, I don't think the front end would be happy with that.
 
but has anyone ever pulled the same track with dual rear wheels then pulled again with singles? maybe at different times tho?
