I have a regular body challenger hellcat currently stock with the 275 tires. I bought a rear set of 20x11 wheels and I am wondering if I can fit 315 /35 R20 110Y XL BSW on the rear without messing around with the plastics. Or should I stick with 305 /35 R20 107Y XL BSW. I plan to run Michelin sport all seasfor regular driving and Mickey Thompson ss on the extra set. But I really don’t want to take it to a performance shop to have them mess with the plastics under the car. Also is belle tire qualified to install these?

"The plastics" being the inner fender?????? I fit 315/35 on 10 1/2", w/o messing with the plastics. The 305 are smaller diameter and look bad with a big fender gap. HOWEVER, it sounds like it is individual for each car. There are people that had major problems also. Read the dozens of threads on this from two different people. I have no clue who belle tire is! :)

I also have a regular body challenger hellcat (2017) with stock 275's and 9.5 rims and I want the 11" Factory reproduction wheels with a 315 for the rear only. All the research I've done says you will most likely have to shave some plastic on the inner fender well to prevent rubbing. Like you, I don;t want to do that either. If you wouldn't mind letting me know what you end up doing, I would greatly appreciate it.

The cost between a 305 and 315 doesn't justify the increase. You're stock and auto, so you really don't need that much tire unless you plan to dig race, and I doubt that because you're going to 20" mickey and not get a 17"/18'' wheel w/ slick like everyone else.

You wont rub a 305 on a skinny boi, and a 315 will slightly rub depending on tire manufacturer, but you can use a heat gun and heat up the inner wheel well, and just push it in a bit so its still capturing dirt and debris but not rubbing (do not cut these..)

Not sure about the belle tire question, just be sure whomever you have throw them on has a good balancer and does a decent job, you dont want a helper throwing your tires on and scarring your wheel to shit because they didnt care. Find a good reputable place and see if they will use their better tech (offer a tip) to get it done, and see if you can watch or be near to prevent them from being careless. Seen a lot of nice cars go through a Mr. Tire or Firestone and some 18 year old throws a rare/nice wheel around like it came off a 99 accord lx.

What's the offset? Knowing your offset is key to answering your question.

I had +18 on 10" rims and mounted 305/35 with no issue on a 2013 R/T. I think your should have no problems with mounting 315's on an 11" rim with a +22 offset. Just to be sure, contact any tire/wheel shop, give them your setup, and they should be able to tell you if you'll need spacers or not.

Stock until august and manual 6 did but I was going to run 305 on regular days and 315 just for the drag strip. Thanks for the info I appreciate it. I’m gust going to have to do trial and error probably
