Has anyone run or can I clear the Toyo RT 35X11.50R20LT on my stock 2020 Ram 3500 Mega SRW with zero rubbing on wheel well plastics or rubbing on radius arm at full lock?
I have the black stock 20's and want to keep them. Or what options just prior to lifting. Considering Thurens level kit, track bar, etc.. Then I'll consider 37's
TIA!

I have the same truck and was wondering about the same, actually i was thinking of 35/12.5-20, did you find out if the tires will fit?

No not yet... im still researching.. i do kmow i think i am going with Thurens setup! Track bar, Springs, Radius drops,then maybe some Bilstiens...
 
techster82 is your truck equipped with the 4x4 offroad package? That package adds a 1” lift all the round if I am not mistaken? Easiest way to tell is if you have the blue and yellow Bilstien shocks.

No off road package on mine, just the regular diesel 4WD suspension.
 
@techster82 Are you able to fit that 35/12.50r20 tire size in the spare location?
I bought the 2020 2500 RAM Night Edition with 285/60R20 wheels a few days ago.
I crawled under to check out the spare and it doesn't look like I'll be able to squeeze a tire much larger than the spare that is already under there (~33")....
I also noticed the spare wheel size was 17"

Not sure, I’ll have to drop it and do some measuring.
 
Seems like a nice budget M/T

Mastercraft Courser MXT 35/12.50r20 on stock 20" Night Edition wheels and stock 2500/6.7 suspension. No rubbing or issues with fitment.

Seems like a nicely price M/T. Do you tow heavy with them? Curious to know the max PSI. Looks great, BTW.:cool:

I'm curious why the need to worry that the spare should match the size of the new tires?
As you noted, it does not match from the factory... wouldn't it just be like the old "donut spare" that gets you to the nearest repair shop?

Many limited slip differentials do not like having unequal sided tires.

Sure, but will it matter for a short trip to get a repair?
Again, it's not like the OEM spare is identical in all trim levels. Maybe there is a difference where it matters?

All the spares match the tire size that comes on the truck no matter the trim level, if your hauling heavy and ruin a tire you need to put the same size on to keep all the driveline parts happy

Sorry but not true. On my 2020 3500 ltd, the tires are 285/60R20 and the spare is 275/70R18.

Take a second to calculate the diameters they are the same diameter thats all that matters they use 18s for all the spares but change tire sizes to match the tires that get put on the truck
