Hi. I'm a new member and this question has probably been ask before so bear with me please. I have a 2019 R/T 5.7 with stock goodyear 245/45/20. I just replaced the rear tires with Nitto 275/40/20 Motivo. The original plan was to run the stock 245/45/20 on the front but now they look too small. I like the staggered look of fat tires on the rear and narrower on the front. My point is that I'm unsure weather to run 255/45/20 or 255/40/20 on the front ? Keep in mind that at some point down the line I may want to lower the car with the Mopar springs. Thank You !

That is a nice setup. I did the 275/40/20 on the rear with the 245/45/20 on the front.

Do you have any other photo's that you can post of the front wheels ?
Looks great ! No rubbing or handling issues on the front ?

No rubbing or handling issues at all. Mopar lowing kit from Summit Racing also installed. I actually took out Eibach springs that were lower because the shocks were the wrong size when I purchased the vehicle.

Yes, Installed on the factory wheels.
Can you please keep us posted on how the 275s on 8 inch wheels works out? I'm sure it will look great, but I'm concerned about premature wear and whether or not the meatier tires improve performance. I have heard that slightly underinflating the tires can help with both of these concerns.

255 is as wide as you should go on 8" wheels, just sayin'

I also had bushings installed to align the rear end and prevent negative camber.

I put 275/40/20 Pzero tires on the back of my 2010 FF R/T stock rims 3 years ago and have not had any issues running that setup up to this point, everything is stock have not changed anything with the suspension.

My question regarded whether to run 275/40/20 or 275/45/20 on the front, but thank you for a reply.

255/45/20 would be a better fit. It's circumference is only 1% more than 245/45/20 so it shouldn't cause speedo issues while a 255/40/20 is almost 3% smaller.

Width-wise, it's only .4 inches wider so I'm not sure if you'll see that staggered look you're looking for.

You can use this site to compare sizes:

You want to keep the tire diameters as close as possible so you won't affect the accuracy of your speedometer.

If you have 275/40-20s on the rear (28.7" diameter), you need 245/45-20s on the front (28.7" diameter). The 255/40-20 tire has a smaller 28" diameter.

I have 315/35-20 on the rear and 245/45-20 on the front. The rear rims are 10.5x20 with a +25mm offset and I run a .25" spacer.
