Bigger wheels get over larger obstacles better, but they also raise the center of gravity, making the rig more tipsy. They're also harder on the drivetrain and motor. The motor can be protected by gearing down via a smaller pinion and/or larger spur gear.

I like the performance and stability of small tires mounted on heavy wheels. Then again, it gives my SCX10 pretty bad ground clearance. So I guess you must consider what's better for your particular terrain.

I've started running 2.2 beadlocks with 1.9 tires more often than not anymore because I feel like they hold the bead better than 1.9 beadlocks tend to. Maybe I'm fooling myself, maybe it's a legit thing, I don't have any scientific research to back it up. If I was building a legit scaler, i think I'd run 1.9 raceline beadlocks I have with scale hardware with some nice 1.7 tires for the same reason. Maybe I'm kidding myself, I don't know.

I use pretty much the same philosophy in terms of 1.9 tires on 2.2 wheels. The 2.2 wheel does not appear to change the OD of the 1.9 tire but the bigger wheel seems to offer better lateral stability on side hills.

I like bashing therefore 2.2 big tires are my best choice.

I'll weigh in here. I run a 1.55 tire/wheel combo on a scx10. I go by the motto of "tiny tires make better drivers" yes it makes it more challenging to drive but I'm not really a basher so it doesnt phase me to spend 10-15 minutes on a obstacle that a 2.2 rock bouncer shoots right up. I also drive a very heavy hard body CC-01 with 1.55 mtz's this may explain a lot about me :ror:
^ same.
i have a 1.55 equipped ascender, with pretty much the smallest tire out there... the dirt grabber from RC4WD. thankfully the ascender's diffs are on the smaller side.
i do have a plan to run 1.9's with a smaller tire. i just posted in the tire section about that idea.
for me its all about scale proportions. some trucks look better with smaller wheels, other look better with larger wheels. choose tire size accordingly. worry about performance after you get the look you are after UNLESS you are building a competition oriented rig. then just get something super sticky at 4.19 OD.

Larger wheels give more clearance under the diffs, and roll over obstacles easier. That said, IMO they look horribly out of perportion if you're trying to be at all scale.
For example, a 1.9 with 4.75" tire on a 1:10 scale rig means the wheels are 19" and the tires 47". They look silly. But man do they crawl.
OTOH a 1.9 wheel with a 4.19" 'class1' legal tire has trouble getting over the easiest of obstacles, so I don't think they're as fun to drive. The few comps I've been to - I'm new - I had both a C1 and C2 rig in order to compete, and they run different courses with the C1 being fairly easy in comparison. So it was still fun and the smaller more scale-looking tires and wheels look much more....scale. LOL
Some bodies and rigs can pull off the XL tires. Some look toy-like. A happy medium for me are the 4.4-4.5" tire size on a 1.9 wheel. To each their own.
Here's a couple of pics of the same chassis with the same size tires - both XL 4.75 tires - just different bodies and wheels, it's a 312mm wheelbase, the WB4 on Ascender. IMO the blazer pulls off the bigger tires way better than the Jeep Unlimited - it kind of looks very toy-like with the way oversize tires:
And with a 298mm wheelbase, 4.19 and 4.45 tires. It climbs and drives WAY better with the bigger tires - these are pitbull braven ironside 4.19 and pitbull rockbeast 4.45:

There are always tradeoffs to modifications.
Larger wheels give you more ground clearance, but they weight more and raise your center of gravity.
