Looking for slightly wider tire than AT4 stock

[sheamus]

My 2019 Sierra came with 275/65/r18 Duratrac Wranglers. They are getting due for a replacement. So I am looking for options others of tried. My criteria is:

• I'd like an hybrid/offroad tire. I am 85% blacktop, 10% gravel, 5% mud.
• It rains a fair bit here
• We do get heavy dumps of wet snow 4-5 times a year (I am in Nova Scotia, Canada if that helps).
• I would like to be very close to the stock diameter just for the sake of not adjusting speedo, etc.
• I want to keep stock rims
• I want something a little wider, so I assume those options would be a 295 or a 305.

 

I made up a spreadsheet and it seems that 305/60/r18 is very close to stock circumference, but there are _very_ limited options in this size. They ones that I have found locally are:

• BFG KM3 - probably too offroad, looking for something more like the KO2
• Cooper Discoverer S/T MAXX - this seems like a good option, but it has been discontinued in this size, as no one has stock in this size, and Coopers website no longer lists it.
• Cooper Discoverer STT PRO - probably too offroad as well
• Nitto Ridge Grappler - don't know much about this one
• Nitto Recon Grapper - need to do more research on this one too

 

Has anyone run this tire size?  What model did you go with? How did it perform? How was on-road compared to stocks?

Just remember that going to a 305 will make it track different on the road and mileage will go down because the contact patch is a decent amount wider than stock.

 

The Recon Grappler is a new Nitto Tire as of this year, it's better than the Ridge Grappler in my opinion. The Ridge Grapplers are pretty terrible in heavy snow and ice, lots of blocky tread with no sipes. The Recon has more edges to bit into stuff.

 

If Toyo makes the Open Country AT3 in that size or if Falken makes the Wildpeak AT in that size, those are great tires as well.

 

I'd probably stay with a 285/65/18 just for price, tire weight to try and keep some fuel mileage.

I'm running a 305/70/17 Nitto Ridge Grappler. Had to trim a fair bit to get this tire to fit with a 0 offset wheel. That included getting a mudflap delete and trimming the plastic. Also deleted the crash bar behind the mudflap but I could probably put that back on. You may get lucky if you keep the stock wheel as it will be pushed in closer to the engine bay. 

 

I live in Southern California so I can't comment on how these tire perform in the rain or snow. They are quieter and ride better than the stock Wranglers.

 

Noticed a slight decline in MPG but not bad.
