    Reaching out to the Tundra community for any feedback on handling issues after adding tires and wheels.

    So I upgraded from 285/65R 18 Nitto MTs on the stock wheels to 33x 12.5 20 Toyo RT tires on 20 inch Fuel Wheels and I am not pleased with the way the truck handles. I wanted to see if anyone else was having issues or changes like this. So the issues I am having are stopping I have actually had the truck lock up in a skid in the rain. Granted I do brake pretty heavy but nothing like this has ever happened before. Also while cornering or starting out the tires break free very easily in the rain where before I had to romp on it to get traction control to kick in. Also on cornering I have had the rear end slide a little where I had never had that happen before. I do drive somewhat aggressive but it has made me a little nervous especially in the rain. It handles in the rain like it used to in the snow. What I am wondering if this is just normal for adding wider tires making the stance wider and adding some weight on each corner.

    Just wondering if this is pretty standard when you get wider tires and heavier wheels or if something might be off.

    Sorry, I don't have a good answer, but am curious to see where this goes. I'm planning to swap from my current Toyo MTs to RTs when these are worn out next year.

    I don't think those are the MS rating tires. They don't have a lot of siping

    Remember too, more aggressive tires have less rubber actually on the road. Less rubber means less traction on dry or wet roads

    Nothing against Cooper tires but, I had a set of them (AT's) that would do the same thing. On wet pavement with a little incline, those tires would break traction very easily almost like I was on ice. I do not drive aggressively and could never figure out why they did that. I suppose a combination of tread style and composition. I probably wouldn't buy another set of Cooper's but no experience with Nitto's.

    Adding larger (heavier) wheels/tires adds rotational mass and contributes to some of your issues. In theory :homer: wider tires give more traction if the contact patch is greater. However in this case with a rugged terrain tire it's likely you're not increasing the contact patch.

    MT's may be good for wheeling through a stream , but they all suck on wet asphalt.

    Purely in my own anecdotal experience, I've never had traction issues with the Toyo MT's on wet roads. This is the second truck I've ran them on (Taco before) and the factory siping seems to grip really well in the water. I am more concerned about the Toyo RT's with their harder rubber compound which is why I'm trying to get as many opinions/experiences with them as I can before making the shift.

    Current PSI is 35 and its odd to me that my old Nitto MTs were more grippy on wet pavement than Toyo RTs. The differences are wider tires and wider stance and it feels like I am driving on snow instead of wet pavement. I do drive pretty aggressive but I am nervous now about cornering and stopping in wet pavement.
