Help please - Max front wheel and tire size?

[Johnabis]

any issues with 275/30/r20 using 9.5 inch wheels for the front? this is a p3d which is slightly lowered stock. I am going 10.0 on the back and will also run 275/30/r20.

Both of these are example of 19x9.5 ET35 on 265/35/19 tire. No rubbing. You will experience range loss on 265 tire, but you can reduce the loss slightly by running lighter wheel.

Another pro for running 265/35/19 is that the circumference are very close to stock tire which will have very little speedo error(0.25%)

Anyone have data on efficiency/mileage hit on wider tires? 245 vs 255 vs 265 ???

Just changed to 255/40/19 Continental extreme contact dws06 (this tire is 27" dia. vs. 26.4" for stock and did not notice the speedo off vs. gps app on iPhone)and went on a 1,200 mile road with a 301 wh/mi ave. last trip with stock Conti's in 235/40/19 I got approx. 275 wh/mi so a solid 10 to 12% hit, but these are new and the others had 17k on them so probably less of a difference when they break in.

I run staggered 245 Front and 275 rear with Michelin AS3+ tires on Model 3 Dual Motor. I average approx. 320wh/mi at quick highway speeds. You'll lose a bunch of efficiency with more aggressive tread touching the ground.

Mountain Pass Performance runs 275/35R19s on 10" +35 rims for all four wheels. I think they have gotten a little bit of rubbing in the front under track conditions (probably opposite lock). I'm running 265/40R18 +39 on all four wheels, no rubbing. For P3D you need a little less offset I think.

IIRC you discussed it a bit shortly after you swapped those on, but wondered if you had any update on what going from 235->265 has done to range/efficiency long term? (and also how noticable if at all the benefits seem like long term vs the 235s)

Went from 290Wh/mi to 330Wh/mi after installing them. I don’t know how much is increased aero drag and how much is from the stickier PS4S tires. I haven’t had them on for a couple months since I’ve taken a few trips up to the snow. I’m going to put them back on soon.

I just test fit a 19x10 +25 with 240/40 and was able to clear the front.

240 on a 19 is quite a bit of stretch!

You'll most likely need a 3mm spacer with 275 on the front on P3D+

Not too bad...

One of our guys ran 295's on the front last weekend!
