Help Me Understand Please

[RobHinton]

I cant wrap my head around this wheel size stuff.
Situation ... about to purchase a 2022 Ram 1500 Classic Reg Cab. It has been lowered w the IHC kit and currently has the stock wheels .. I believe the sizing is 20x8 Offset +19mm 5x139.7mm (5x5.5"). I am wanting to swap them out for a nice set of 22x10 w +25 offset.

With the increase in width and offset will I run into rubbing issues?

If not, I would like to go to a little wider than stock tire, but again worried about rubbing.

All help very much appreciated. Pics would be great!

My mobility has been very limited so I am having to go from my crew back to a reg cab that sits much lower, but I have found one that I am very excited to get. I cant wait to add it to the collection of awesome trucks here!

Here's Google AI answer

Because the 22x10 wheel is 2 inches (50.8mm) wider than the 22x8 wheel, the width increase is split between the inner and outer sides, but the higher positive offset (+25 vs +19) pulls the 10-inch wheel slightly more toward the suspension.
Comparison Results (Approximate)
Inner Clearance: The 22x10 +25 wheel will sit 38 mm (approx 1.5 inches) closer to your suspension/strut than the 22x8 +19 wheel.
Outer Poke: The 22x10 +25 wheel will stick out (poke) 12 mm (approx 0.5 inches) more toward the fender than the 22x8 +19 wheel.

Summary of Change
When switching from 22x8 +19 to 22x10 +25:
Wider: The wheel is 2 inches wider total.
More Inboard: 38mm less space to suspension.
More Outboard: 12mm more stick-out from the fender.
Key Takeaway: The 10-inch wheel will require much more clearance on the inside of the wheel well than the 8-inch wheel.

In other words it's probably highly likely to rub. You need a minimum of 10 mm negative offset to go 10 wide. In my humble opinion.

Or if you mind is made up on these wheels, you need spacers.

Thank you for the detailed explanation. It helps me understand it much more. The wheels I am interested in are the SRT10 replicas and I see a lot of folks going with those. Is spacers common? any downside to using them other than it poking the tires out a bit?

I think you will get a lot of mixed opinions on spacers. Some will say absolutely never, others will say ok no problem, it's personal choice.

I run them now on my 4x4 overland truck. But the spacers are .375 inches or 10mm. Just enough to provide additional clearance for the tires to not contact the upper control arm. As I was dead set on +18 wheels and 315 70 17 tires.

If I had to do it over, now, I'd probably still get the same wheels but go with 11.5 wide tires, thus no spacers. My spacers are actually not a problem but it's just one more thing to take care of long term.

So to answer your question, it's a personal choice.

You tube is your friend here, there's an unlimited number of videos on spacers.

Thank you ... I just watched that a bit ago actually.

Im considering a little more narrow tires up front and maybe a .5" spacer.

Never ran spacers until recent lift install; I suggest torquing and indexing the lugs on the spacers for peace of mind. I check from time to time and humbly confident when I see my previous marks remained aligned.
