Hello, I'm new here, but spent a lot of time browsing the forums when deciding what to do as far as larger tires/levelling kit. This forum has been extremely helpful for which I am very grateful. I have a 2014 Fx4 supercrew 157" wheelbase and recently installed the Bilstein 5100's at the highest setting in the front. A week later I had a local tire shop install 295/60r20 Ridge Grapplers on my stock FX4 20" wheels. I drove the truck for a week or so with the Bilsteins on my old pirellis and everything seemed fine/normal (other than the truck sitting higher and riding/handling WAY better). I did the install myself and was extremely careful with the IWE's. Made sure the axle teeth meshed up, measured the axle bolt protrusion, and did not overtighten the axle nut. Tested 4wd etc. and everything was fine/normal.

Got the new tires and immediately noticed they seemed noisy. I was surprised at this since all I've heard is how quiet these tires are. I've driven trucks with ko2's and at2's and these things were WAY louder. Starting at 40 kmh (25 mph) they begin to hum and seem noisiest around 40 mph. Seem a little quieter at higher speeds. Even more troubling is that they seem to be getting louder. I only have about 500 km on them (300 miles). It seems to be all 4 tires, with the window down it sounds loud front and rear. I thought maybe I was rubbing but the only place I am close is on the UCA and even at full lock backing up in reverse I haven't felt/heard anything. When tracking straight I can fit my pinky finger between the UCA and the tire. I have searched the internet extensively and haven't found any complaints about noise with these tires. I also have a cousin who put the same tires on his truck the same week and he can't even tell the difference from his stock hankooks. I've heard the same from others that have these tires. I went back to the tire shop and the installer told me he drove the truck before and after and that he was surprised how noisy they are. Unfortunately the tire shop does not carry the Nitto brand....I had called them last minute because I had success with them in the past and they said they could get the Nittos. They gave me the best price around so I went with them. Now they are telling me 'that's why we only sell Toyos' and that 'Nittos are a lesser quality brand' which I believe is nonsense. They were not at all helpful with warranty claim other than giving me the phone # and telling me to deal with it myself. They said if they were Toyos they would replace them no problem. I don't get what the difference is.

Anyway, I am pretty convinced there is something wrong with these tires and wondered if anyone else has had a similar issue with brand new tires? The date stamp on all 4 is from July 2017. If anyone has any insight I'd really appreciate it. Thanks in advance.

I just did the Bilsteins and Ridge Grapplers about a month ago. Only increased diameter 1 inch but they are just a little bit louder and by no means annoying. I'm running 275/70/18 on mine.

What tire pressure are you running? I have the exo grapplers and they we're loud after installing. I checked and the tire shop set them around 35psi. I bumped it way up and it seemed to help with the noise level and wear pattern.

Thanks for the reply...tire shop had it at 35 psi, I bumped up to 40 psi after checking the toyo load tables....no change and if anything they have just become noisier.

I think mine are at 55 with a Max of 65 I believe

I don't think there is anything wrong with the tires. You are coming from a non aggressive tread a/t to an aggressive tread a/t. They are an inch wider and 2 inches taller and weigh around 15 lbs more. Also the 295s are LT tires, your old ones were passenger tires.

My 295/60r20 Toyo MTs aren't even noticeable over the radio and they are mud tires. I think you are just used to the pirellis and I guarantee you you'll get used to these

I went from OEM Hankooks to Ridge grapplers and don't think they are that much louder at all. Quieter than KO2's I've run in the past.

Where are you located? If you're in the Van area, we can compare. Honestly, these tires are exceptionally quite for the thread pattern.

How are these tires in the rain?
