Addicts rim

So now I have 2 sets of tires on order at the shop and will look for best fit. Sizes 265/50/20 and the 285/50/20 both the Nitto terra grapplers. These will go on the XD Addicts. Anyone running the 265 grapplers?

Danny, an you clarify what you are saying thru all this data. I understand IT, just not sure what you are saying?
are you trying to imply that changing the tire diameter is unsafe?
because your speedometer will be off?
your engine will rev too high with a smaller dia. tire if your going too fast?

The unsafe part i see here in this example would only be related to sidewall depth if you are using this vehicle off-road at all. the rest is just information for you to use as a tool. So you are informed as to the effect the tire will have from oem.
 
What 1010tires points out is that over 3% in increase in tire diameter may result in negative effect on brakes/hubs, etc. The additional weight and size of the tire is possibly pushing beyond the margins that the OEM part were rated for.

You are also putting additional stress on the drive line and possibly will want to change gearing in order to compensate for the lack in "get up and go". with a larger diameter, it will take more effort to get up to speed compared to a smaller diameter.

Hopefully this helps

Sorry I did not look into that much details..

Ok, it's not safe but its too much stress on the car. They just need to make a 265 60/20 Tire size :banana:

Quite a few have upgraded tire size with no problem it seems. Is that not the case?

3 things:

1) What other parts did they upgrade? if you watch "trucks" you'll see 30 and 37 regularly, but always on upgraded axels, etc.
2) Just because it fits and works (initially) does not mean it works as intended long term.
3) lawyer speak. Cars are designed with a safety margin. 1010tires simply points out that you might be exceeding that margin and they are covering their ass with the warming.

As with everything: "your mileage may vary". :D

Not only what Oki said..

It will cause "cupping" for SURE. If not tire separation etc...

So the cupping can happen at any times and they will cause a grave deal of discomfort.

Maybe not so much a safe concern, but it's a ease of money (gas millage increase and less life time for the tire).

IMHO it's not worth it unless you A. have deep pockets or B. want to put your family's safety on the line.

If you do have deep pockets, replace the rims, which is what I would end up doing.

To each is own. :cheers:

Not really, I guess 275? Honestly, just go with the 285s. Orthboy said he didn't have to adjust at all. All you have to do is loosen a screw, push out on the plastic inner fender and tighten it up. Anyone could do it, even if your not that handy.

Back to the tire shop Thursday as he has both the 285/55 and 265/50 terra grapplers in for me to decide. He said he will put one on each front rim and we can check for rubbing. Was wondering what part of front fender did you unscrew? Part closest to outside of wheel well? Once unscrewed, you pushed in plastic inner liner away from wheel? Thanks.

any issues with vibration with these wheels? love how cheap they r (made in china) but questioning quality.
 
I've had a set in 20's and 18's and both sets have been absolutely perfect. I do love these wheels but I might be upgrading to some Method Wheels here in a bit.

Like Ride, I also have the 20's and 285/50 20's........I'm sorry to say that I was not creative enough to find my own wheels and had to copy Ride, orthoboy and kingpin because this setup is absolutely amazing......great handling and looks awesome....
