new tires

I got my new tires put on today, doing my complete front end this weekend.

I put on 295 70 17 nitto trail grapplers, the truck feels like it is wishy washy now, almost like the tires have a soft sidewall. Is this normal for these tires?

thanks
Ben

Depending on what tire you were coming from & how worn out they were, a new MT with lots of tall tread blocks will seem squirmy on your truck. (Like there is a delay between your steering input & the truck's response.) I've found that I just get used to it with time. Make sure you're running good air pressure in them though.

This is my first set of mud tires. What do you recommend for air pressure.

When I was researching new nittos, people said it felt squishy but went away after some miles were put on them

Don't know if I got used to it, or it went away, but no problems here in 50k miles. I run about 50psi front and 35 rear (empty).

I have the terra grapplers and they felt squishy at first too. I could have gotten used to it or it went away and I have about 8k on mine. I run 54 front and 50 rear.

Ive got 305/70/18 Toyo AT's. It took some getting used to the softer sidewall but its got a nice ride! I've had all kinds of mud tires on and these are the softest by far. Be careful. you'll get used to it.

I just got Nitto Dura Grapps in 285/70/17.

They started them at 70psi in the rear and 45 in the front which is backwards from what I think it should be so I switched it (and will run 80 in the rear when towing or loaded).

I felt real squishy driving off the lot but it went away within 50 miles even before I adjusted the pressures. They have a mold release on them when new that is slippery. I've decided this accounts for the squishy. Now it feels very stable. I know when you buy motorcycle tires they warn you about the mold release whenever you get new ones.

I would run them at 70f/65r (unloaded) and wait for the mold release to wear off before you pass judgement on them.
