Both the Dodge Challenger RM and the TC both have this issue, the tires are the original spec size giving no additional grip. The Camaro's and all other RM/TC car's get much wider tires while the Challenger remains with it's skinnies. The TC CR-Z has almost double the tire width... the RM Camaro's almost triple.

This only slightly bothered me when it was just the RM but now with the TC also getting no love my question has to be why?
 
Maybe it's best to not have such wide tires on the Challenger. It's kind of heavy and can be a little understeery. I would imagine that wider tires would increase that aspect of the cornering.

That is an incorrect statement on several levels. Nice try though...

Last time I drove the Challenger was around 6-7 months ago so I'm not too knowledgeable of the car. Plus I decided against having the TC version in my garage. By the way, what's incorrect?

The Challenger does understeer quite a bit. If you put wider tires on it WOULD be worse. Physics FTW
 
The major reason I asked is the 69 Camaro RM has tons of grip received mostly from it's ground gripping wide rear tires, you hit the throttle it sticks then just launches. The Challenger on the other hand gets a bit extra power and rear tires roughly identical to it's front's which along with it's torque light up the tires rather easily. I've tuned the understeer out early on this is just a random I wonder why question.
 
Umm wider tyres doesnt mean more understeer...
 
A wider contact patch in the rear does promote understeer. However, as Nish is touching on, in the case of a high-torque car like the Challenger, you do want a fairly wide set of rear tires to contain the power, and to enhance the acceleration out of a turn. With the narrower tires it currently has, it will be slightly more maneuverable in the handling balance sense, but the obvious trade-off is it can't put down its power as cleanly as the Camaro.
 
You size front and rear tires to match the characteristics of the car. It isn't as simple as, Wider = more understear.
 
So wait... some say wider tires doesn't make more understeer... and some say wider tires do make understeer. Which is it? :confused:
 
If you widened all the tires equally, it would probably be about the same characteristics as before (understeer in this case). If you widened only the rear, it will probably create understeer. Like I stated right before your post, you size the tires to match the cars characteristics.
 
Sorry, I didn't really understand what you said as I was in a rush and didn't process things to great. :lol: Thanks for the explanation. 👍

Nice profile picture :lol: . Well back on topic, I think the challenger should keep it's smaller tyres otherwise the car wouldn't look right. Or maybe if the tyres were wider it wouldn't fit and the tyres would have to stick out from the car.

That could be another possibility. I will now have to check the fenders and such on the Challenger.

Thanks, it changes too. From weekdays to weekends. :)
 
I was thinking the tire size of the Sam Posey #77 would be a good size.

The 2nd picture shows it the best, not massive drag slick's to sat the least but the stock size tires are much smaller.

Ok so I have a correction to make, the Challenger RM has the proper tires as long as you don't change the rim's (they seem to revert to stock size if you change the rim's) but the TC still has skinnies.
