We get a lot of questions in our inbox about tires.
Most of the time, they are repeat questions.
So chances are that you have asked some of these questions yourself. That's why we decided to put all your tire questions in one place!
Let's get right into it!
1. Why is it a Bad Idea to Run a Wide Tire on a Skinny Wheel?
It's actually perfectly fine to run a wide tire on the skinny wheel unless you're going super extreme but we don't think that's what you meant.
So, it's actually really common in the off-road world to have a lot of tires and a little bit of wheel because you don't want to be damaging your wheels and you need that nice big sidewall for getting through the mud or crawling over rocks or whatever you're doing with your truck offroad.
You can easily run a 12.5-inch wide tire on a 9 or an 8-inch wide wheel that's perfectly fine to do
Fuller actually owned a beater Ranger way back when that had 15x8s on it and he ran a 10.5-inch wide tire so there was plenty of sidewall sticking out and had a big bulge on the side and that's fine to do.
It mounts up fine, you don't run into any issues with mounting balancing, you don't tend to have problems at all.
Now on a lot of the newer trucks like the new Silverados and the new Fords you can't run a really tiny wheel (as in diameter). Trying to fit a 15 on there won't work simply because it doesn't fit over the brakes. But if you did go down to like a 17x8 you can still run that 12.5-inch wide tire if you're looking for that big, balloony sidewall.
If you're looking for an aggressive off-road setup there's absolutely nothing wrong with doing that it's perfectly safe and you didn't run into any problems.
2. Is it Safe to Run a Stretched Tire?
This question is actually way more common than the first one.
So if you don't know what a stretched tire is, it's where you take a wide wheel and put a skinnier tire on it. This causes the wheel to stick out more and for the sidewall of the tire to curve backward.
This style primarily suits street or show trucks. A little bit of stretch makes the wheel more prominent, which is the look these kinds of trucks go for.
If you're doing any sort of off-roading, we do not recommend a stretched tire.
While there isn't anything wrong with a stretched setup, for off-road use you are putting your wheels in a perfect spot for damage. There will be no sidewall to protect the wheel so you're definitely not going to have a good time.
Also, keep in mind, stretching your tire puts extra stress on the sidewall, so you won't be able to use the full load capacity of the tire.
