Red Horse Posted July 29, 2014 Share Posted July 29, 2014 The build sheet for my B , (11R x 24) lists the wheel rims as 14QJ314P3. In checking by position, I have 8.25's on the front and 8.25/8.0 on left rear and 8.0/7.5 on right.For sure the 7.5 has to go but any thoughts on having 8.25/8.0 as a combo. I assume worst case is I will not have same tire heights. Also, are wedges unique to a specific rim width?Thx Quote Link to comment https://www.bigmacktrucks.com/topic/36502-rim-width-question/ Share on other sites More sharing options...
j hancock Posted July 29, 2014 Share Posted July 29, 2014 It may change the tire profile somewhat.There are indeed a bunch of wedge depths available depending on rims, spacer widths, etc. It seems that "most" rear wheel wedges are OK if there is an air gap between the heel and spoke. Or if there is contact between heel and spoke, it is reached with about 80% of the final torque value which is around 200-250 ft lbs.http://truckhub.us/yahoo_site_admin/assets/docs/Euclid100DWheelAttachingPartsX-Ref.96161249.pdfCheck pages 44-51.

blackdog2 Posted July 29, 2014 Share Posted July 29, 2014 Hey big RED make sure your tire to spring clearance is good and that your tires don't rub together on the bottom when loaded or you will side wall fail or.

EJ- that has never been a problem. I thought I had a spacer width problem then Danny Melone spotted that 7.5 rim on the outside. And the rears are all relatively new caps and you can see the height difference. I also can't get the wobble out of that wheel but I will worry about that once I replace the rim.

Brian Lawler Posted July 30, 2014 Share Posted July 30, 2014 A 8.5" rim has a smaller diameter tha an 8". An 8" rim will fit on a rear spoke meant for a 8.5" but an 8.5 will not fit on a rear spoke meant for an 8". If you put an 8.5 on a front spoke meant for an 8, it will go on but the dogs will not sit right. The 29k and 35k single rears take an 8.5 wheel.Brian Quote Link to comment https://www.bigmacktrucks.com/topic/36502-rim-width-question/#findComment-254488 Share on other sites More sharing options...

doubleclutchinweasel Posted July 30, 2014 Share Posted July 30, 2014 Went through this on my R. It had a mixture of 20 (tube-type) and 22.5 (tubeless) rims on it. Some were 7.5, others were 8.0, and still others were 8.25.Took them all off, and put on 22.5 X 8.25s. Used same spacers, hence same clamps.
