H8R Posted April 17, 2007 Report Share Posted April 17, 2007 (edited) I am getting a very nice price on a set of General Grabber UHP... they are 285/50/20... I realize the stock SS Tires are 55 series...Will this make a big enough difference in sidewall height. I realize alot of tires are given a size rating but they still are not uniform with all brands.....eg... IMO the width of Nitto tires seem to run narrow with all other factors being equal (275/55/20 nitto v.s 275/55/20 kumho) I have measured and thr tread width on the Kumho is about .5-.75 wider.... so I was wondering if this held true to the Aspect ratio between other brands?

CoolBlueSS Posted April 17, 2007 Report Share Posted April 17, 2007 Probably. As you've stated, and I've seen this also, the same size tire between 2 munufacturers will be a little different. Not enough to make a big difference, I don't think. Btw, I have a set of UHP Grabbers on mine. I like them. Quote Link to comment Share on other sites More sharing options...
H8R Posted April 17, 2007 Author Report Share Posted April 17, 2007 Yea.. I read alot of reviews on them...They sound to be a great choice. Besides even if they are a little shorter, they are a little wider, just will lokk better when it's lower(the Truck) Quote Link to comment Share on other sites More sharing options...
mungman Posted April 17, 2007 Report Share Posted April 17, 2007 the aspect ratio is as follows. on a 285/55 R20 tire, 285 is the width of the tread in milimetres. 55 means the side wall is 55% of the width of the tread (156.75mm) and the R20 is the diameter of the wheel (20"). hope this helps answer your question. ~mung Quote Link to comment Share on other sites More sharing options...

mungman Posted April 17, 2007 Report Share Posted April 17, 2007 i was informed that the measurements are taken from the casing. the manufacurers are given about 3-4% variance on the size up and down to allow for tread wear. that is why the sizes are very close but not exact.

H8R Posted April 17, 2007 Author Report Share Posted April 17, 2007 (edited) That makes sense.... I will just have to measure the overall height.....not that it would even be close...the tires I am removing are WAYYYYYYYY Gone...lol.....So I prob. will not notice a difference. Thanks guys!

CoolBlueSS Posted April 17, 2007 Report Share Posted April 17, 2007 I will tell you this, the UHPs are a hell of alot better than the original Goodyears. Even when they were new. Quote Link to comment Share on other sites More sharing options...
H8R Posted April 17, 2007 Author Report Share Posted April 17, 2007 Thats great To hear... Hell I didn't think the GY's were superbad...but I have never driven an SSS with anything else! Maybe I'll have a new outlook on the SSS handling! That would be great because I took twistys with the G Years' pretty well.! Quote Link to comment Share on other sites More sharing options...
