I'm trying to decide upon what I want for my next set of tires, I've been very happy with my Nitto Terra Grappler G2 tires and I honestly can't really complain about anything, but I'd like something a little more aggressive looking that's a little bigger, and a little extra traction wouldn't hurt, so I'm looking at Nitto Ridge Grapplers in 33" and 34" sizes. The problem is when going past a 33" tire, most of the tires available are only rated for 99mph and that's a speed that's easily reached. It's not abnormal for the flow of traffic on local highways to travel in excess of 85mph so sustained speeds of 90mph with short bursts of higher speeds wouldn't be abnormal for me.

Looking at the options available, would you choose a heavier and seemingly more robustly constructed LT tire with a 99mph speed rating, or a P-Metric tire with a 118mph speed rating?

I guess I'd want to the speed limiter of my truck first. The ECM may not allow the truck to exceed 100. This is something I've never tested in my own F150.

Just get Z rated tires.....lol. Your truck has a max speed programmed into it usually for what the tires ratings are when the vehicle rolled of the assembly line.

It's really not designed to hit 100, that's why they don't bother making too many work tires with a higher speed rating. And why the limiter is set just below 100. But there are 34" tire models that are higher speed rated, I guess just not Nittos. Cooper, Falken, the ever-popular KO2, etc.

You could always be the third fastest guy on the freeway and limit yourself to 90.

The speed rating wouldn't even be on my radar. Buy the tire you like

Most drivers should never drive anywhere near 99 mph. Not properly trained, and lack of proper vehicle upkeep.

I'm not gonna argue with you there, as a state vehicle inspection mechanic I see some unbelievably unsafe vehicles come in off the road with the owners thinking that nothing is wrong. I'm still amazed by the people driving around with bottles of brake fluid in the passenger seat to top off the master because their calipers or brake lines are leaking. Oh and don't get me started on underinflated, bald, or otherwise damaged tires; and then there's all the German cars driving around with broken springs, you wouldn't think "the ultimate driving machine" would need new springs every 5 years, but what do you know they're broken again.

Trying to delete, wrong thread.

Factory speed limiter is ~ 95 MPH, but according to his signature, he is tuned, so that may have been raised/removed.

Drive it like you stole it and enjoy!!! You can't drive it fast enough to hurt it and you can't stop it fast enough to keep it from hurting you!!!!
