Sourcing KMC Impact 542s

[domiNATE]

Mud,

Been crawling this forum for a while now and finally signed up as I just recently picked up a 04 LX470. The tires that came with it are not stock and are in rough condition.

I did my research on offset and hubsize, etc. and found several instances of people running the KMC Impact 542 in 16x8 w 0 offset and 285/75/16 on the stock AHC.

I recently ordered the rims and the tires and the tires just showed up but it turns out the rims are backordered and not set to ship until June.

I was hoping with all the vendors and industry connections that someone might know someone that could help me get these OR you know of 16" alternatives that would work.

Any help would be greatly appreciated.

Nate

Go with the 17's. All things equal, the 16's will have more sidewall and conform to rocks better but not all things are equal. Almost all 285/75R16's are E-load tires. But you can buy 285/70R17's in C and D load. I'm almost willing to bet the 17's on C's will outperform the 16's on E's.... granted we are talking about performance. If durability is the main concern, then go with the E's.

Do you know of any 17” after market wheels that fit on stock LX without spacers? I can’t seem to find anything aside from the EVO Dakar…

I run 17s on my Jeep and my Duramax and love the size. I just read a lot about the added sidewall and saw several guys w the KMCs so knew they would fit.

I don’t know of any 17s that work w stock suspension without spacing besides the EVO Dakar.

Any thoughts?

Well, style is personal preference but both Method and Relation Race wheels offer multi-spoke wheels in 17" size.

Ahh. That’s good to know. Thank you.

I didn’t think many of those rims would allow you to run a 285/75 bc of the wheel width and offset without spacers or trimming the pinch weld, etc.

 

[hoser]

Personally, I wouldn't suggest zero offset wheels (w/ 33"+ tires) for anybody who didn't want to trim and run stock height. They might fit on-road but there is a really good chance they'll rub on anything off-road. I would suggest a +25mm to +35mm offset.

Just for clarification, 285/75R16 is equivalent to 285/70R17.

And lastly, the Method 314 wheel can fit the 100 but requires an additional step. The center bore necks down a bit towards the outer edge. So folks are either grinding a couple mm's off their hub nuts OR machining that center bore where it necks down. You would also have to contend with the center cap.

The Relations Race Wheel only comes in Zero offset. Should you go that route, you would also need to clearance the necked down center bore. For the center cap, there are folks offering 3D printed spacers.

Thank you so much for that detail.

Do you think the 285/70/17 with the mentioned offset would work fine on stock suspension? My thinking is if I do any wheeling I would put it the AHC in High. But I don’t want to rub at normal height.

Thanks

 

[hoser]

I don't know that answer but maybe somebody else can chime in. However, if it does rub, it's likely the pinch weld area. Knocking that pinch well down and then heating the plastic fender liner in shape is not very difficult. It'll look mostly stock too.

I imagine you are talking about the 17x7.5 which has the 25 offset but the backspacing is greater than the 8.5 which has a 0 offset.

17x7.5 25/ 5.2
17x8.5 0/4.75

Not trying to be annoying here but just don’t want to get stuck w rims that don’t work. Already have to send back my new tires.

 

[hoser]

Yes, that 17x7.5 wheel will work well with a 285/70R17 tire. Ignore backspacing for this case. The wheel will not make contact anywhere itself. Offset is more relevant. The tire will center itself on the wheel and it is the tire that can rub. But you can plug the numbers here and get a better visual....

Also look into Icon wheels. Might fit without mods.

I ended up going with the Method 314 in matte black in 17x7.5 Will be running Maxxis Razr AT in 285/70/17. I know those are not as common but I run the MTs on my Wrangler and love them.

I was able to get all 4 wheels for ~$950 shipped with a free set of black extended lug nuts.
The tires cost me ~ $1100.

Will post some pics once it is done.

Thank you for the help!

I’ve read great reviews about the Maxxis AT from the Tacoma guys. Looking forward to your feedback

 

[hoser]

Be sure to search the mega thread on Method wheels for how to fit the 314’s. Maybe dry fit one on the front before mounting the tires.

Looking good

All that siping is what makes these much more appealing than the ridge grapplers that slid all around on me in the summer rains and winter snows

Hoser,
I'm in a similar situation. A buddy of mine gave a me, practically a steal, on some KMC Impacts. I love the look and am fine with the 0 offset. I know I will probably have to adjust the liners and maybe a pinch weld or two, which I am able to do.

The main thing I wanted to get your take on is the ride comfort with an E rated tire and the AHC. If it was a perfect world, I would aim for a SL or C load, since this is my daily as well, but I know that really isn't an option unless you know of a 285/75/16 at offers a C rating? If E rating is the only route to go, do you have a tire brand recommendation that you prefer over others?

 

[hoser]

Most of my tires are E-load, because that was all that was available. Certainly subjective but the ride is not bad unless you daily drive a Lexus LS. But off-road, the C-load tires definitely conform more to rocks than an E-load. But free is free, go with it and then decide later on your next set of tires.

 

[jct23]

I appreciate the feedback. I’ll probably go E load and see how it goes. Worst case I change them out.
I did see Toyo has an open country C/T that can run a 285/75/16 in a C load. Have you heard anything about those?
