Will 33x12.5x20 Tires Fit on a Stock F150?

Seeking Advice on Tire Fitment for Stock F150

I’m currently considering upgrading the tires on my stock Ford F150 and I’m really curious about something specific: will 33x12.5x20 tires fit without any modifications?

I’ve done some research, but I keep coming across mixed opinions. Some people say it should work, while others warn that I might need to lift the truck or use spacers. Here’s what I’m trying to figure out:

Things I’m Considering:

  • Rim Compatibility: Are these tires compatible with the stock rims?
  • Clearance Issues: Is there enough clearance with the current suspension setup?
  • Model Year Variations: Does it vary depending on the model year of the F150? I own a 2020 model, and I want to ensure it’s a straightforward upgrade.

What I’ve Gathered So Far:

  • Some users reported that the 33x12.5x20 tires fit without any issues, while others had to deal with slight rubbing, particularly during turns or off-roading.
  • I’ve heard about the importance of backspacing and offset when it comes to tire fitment on trucks. Anyone with insights on how these factors play into fitting bigger tires?
  • Have any of you made this upgrade or had experience with similar sizes? Any tips or advice would be greatly appreciated!

I just want to make sure I make the right choice before I pull the trigger on new tires. Thanks in advance for any help or insights!

I think 33x12.5x20 tires will fit on a stock F150. The suspension setup is generally good with these size tires. Just be mindful of potential rubbing during tight turns.

Exactly! I had a similar setup and noticed that the turning radius was affected slightly but not overwhelmingly. Just be prepared for a little adjustment.

If you do decide to go with those tires, consider some minor modifications, like spacing to prevent rubbing. It can really make a difference in ride quality too!

I had 33x12.5x20 on my F150, and I can vouch for the ride quality being pretty decent. It didn’t feel too bumpy, but every truck varies. Definitely check your suspension setup first!

I would suggest looking into a leveling kit if you’re going with those tires. It not only helps with rubbing but also looks great! Win-win!

That’s a good point! A leveling kit adds such a nice stance to the truck. It might get a bit contentious though if you go too high.

I had a buddy who went with 33s on his stock F150 and ended up doing a lot of adjustments after he realized it caused rubbing issues. Just a heads-up!

Honestly, the laughter I get from people questioning me about my tire size is worth it! Just do your research before upgrading, and you should be fine with 33s.

Absolutely! Researching helps avoid potential mishaps. But let’s also enjoy the process—it’s all about the adventure!

Just remember, every setup is unique. A reflective approach would be to consider long-term plans for your F150. Happy upgrading everyone!

To fit 33x12.5x20 tires on a stock F150, you need to consider wheel offset and backspacing carefully to avoid rubbing. A negative offset can help push the tires out, but too much can affect stability.

Exactly, but remember that the suspension setup also plays a role in fitment. Some users report rubbing even with the right offset.

It’s critical to get the right backspacing, ideally around 4.5 to 5 inches. This helps maintain stability while ensuring your tires don’t hit the frame or suspension components.

Anyone tried using spacers? I’ve heard mixed reviews about their effect on handling.

Spacers can work, but they introduce additional stress on your wheel bearings. If you’re considering them, make sure to keep an eye on your alignment and wear patterns.

Great point! I’d recommend checking with a professional to see if your setup is safe after any modifications.

Just remember, if you go too wide or with too much backspacing, you might potentially rub against the wheel wells when turning. A lift could help avoid that issue altogether.

Yeah, and nobody wants that sound! It’s a nightmare for any truck owner! Ha!
