I have a 2001 e285 4 seater that came with 12" tires. I want to change to 10" tires and wheels. I know it will slow it down and lower the center of gravity, which is what I want.
Any issue with doing that?
The rim size doesn’t matter
Use this to compare
I used below but had to use spacers so the rim would clear the caliper.
The wider track & more rubber improved the ride & cornering
Thanks… I am looking to go about 8mph max. I want to use it for a parade float so I don’t really need wide or special… just smaller. 
I figure the steering on this thing is bad enough… adding wider tires may be an issue for turning
With the drum brakes in the front of your 2001 means the 10" rims will work fine without spacers, I have 8" rims [turf tires] on a golf cart with drum brakes, but the height is still 18"
any 4x100 bolt pattern rim will work
Here’s a lower profile version of the tires on the same rims
I’m not seeing any 205 40 10 tires
I’m running 15psi on my GEM & the steering is fine as long as you’re moving at all
Just rewire the pod switch to be in turf mode all the time.
Of if you can get a programmer set “Max Oversped” to 8 and change the accel variables down
Yeah, turf is about 14mph on my other cart and I assume this would be the same. I could be wrong about that though. I can add a resistor and drop to anything I want… but smaller tires and wheels will drop my center of gravity a bit… added benefit is the slower speed.
Change the potentiometer in the pedal to a higher resistance.
Or stick a few lego blocks inside it.
(RIP assyreqd)
It looks like they are using the pot as a pot and not just a variable resistor. If that is the case I would just add a resistor to the hi side of the pot and it should give me what I want.

Emmet is everywhere.
A past life had me assigned to a few jobs for Legoland. I got in the habit of always having a couple extra little workers in my tool bag. Before I sealed up the job, I’d stick one of the little guys in a random spot to watch over the work. I hope it gives the next guy a double take.
Yes, but pot is variable constant torque. Not speed. Speed needs to be programmed of field current raised.
Too funny. I was wondering what the RIP Assyreqd was all about
Ok… something doesn’t sound right… The “pot” I was referring to is the speed pot in the foot pedal. Are you saying it is a constant torque input and not for constant speed? That doesn’t seem to me like it would make sense in an EV… Or were you thinking of a different “pot”?
Exactly, almost all “on-road” ev are constant torque mode.
I’m not saying it won’t work, only that you may lose considerable torque.
Picture loading up a trailer ramp. If constant speed, it will go up slowly. Constant torque, will wait for enough torque demand from throttle. IMO
Programming is pretty straight forward. We just need to get you the Sentry sw.
