geest31c Posted Tuesday at 03:04 AM Posted Tuesday at 03:04 AM Sorry for the basic nature of this question, but info seems illusive. My camper has the ridiculous 12.5" rims on the rear with 225/50R non truck rated tires and 13" rims on the front with LT tires. My goal is at least 14" (15s, if possible) rims all around with proper truck tires with sidewalls still intact (not just reduced per rim size increase). Aside from speedo effect and high end ratio impact, I would like to complete this, as many seem to have done. Advice would be sincerely appreciated. I have 4 bolt hubs. Thank you, Geest31c Quote
WME Posted Tuesday at 03:46 AM Posted Tuesday at 03:46 AM Do you have dual rear tires? (4 tires) The four bolt hubs are going to be the main sticking point. Most of us have Hilux based campers, the Townace is a JDM model Quote
geest31c Posted Tuesday at 04:18 AM Author Posted Tuesday at 04:18 AM Thank you. I have single axel four bolt. Auto trans with overdrive. I can find 4 bolt wheels up to 15" but the wheel tire combo affects the gear box. Still, I see similar rigs with the larger rims and tires. I'm running a 4 cy diesel 2C motor with about 75hp. Quote
linda s Posted Tuesday at 04:59 AM Posted Tuesday at 04:59 AM Looks like the OEM size for your wheels is 14 inches with a 175x14 inch 6 ply tire. 1993 Toyota Town Ace - Wheel & Tire Sizes, PCD, Offset and Rims specs | Wheel-Size.com Possible wheels 14in Wheels 4x4.5 for sale | eBay Tires, These are stronger than stock but guessing your camper is quite a bit heavier than a plain van.

geest31c Posted Tuesday at 05:15 AM Author Posted Tuesday at 05:15 AM Linda, thank you. Do you think my 13" in front and 12.5" on rear are swappable with the 14"? Currently my 13" front rim has a 165R13LT, which I think is 65 on the sidewall, but it is not marked. The rear runs the 12.5" rim with the 225/50/12.5. You think 14s all around is okay? Quote
linda s Posted Tuesday at 05:42 AM Posted Tuesday at 05:42 AM That's what it originally came with. Some hack put on the mess you have now. Original is always the safer option Linda S Quote
geest31c Posted Tuesday at 05:59 AM Author Posted Tuesday at 05:59 AM Seen a number the exact same, but I agree with you. With the 12.5" rear and 13" front, 4 bolt on 4.5" centers, you think I can just swap the 14" rims front and back with a 4.5" bolt pattern and larger tires? I know you are knowledgeable, as I have read your posts. I would love a 5 bolt pattern but the rig is not so blessed, as the same year 4x4 are. Quote
linda s Posted Tuesday at 06:13 AM Posted Tuesday at 06:13 AM Can't imagine how it would not fit since that's what Toyota put on it at the factory. Original equipment is always the way to go Linda S Quote
geest31c Posted Tuesday at 06:25 AM Author Posted Tuesday at 06:25 AM I do see a site that confirms the 4 bolt 4.5" lug pattern on a 165R13, which is what I have. Is it possible u r looking at the 4wd setup that does have oem 14", usually five lug? When I look at the Townace light pickup, it has the exact hacky wheels and tires that I have - 12.5" 4 bolt rear, 13" 4 bolt front. If my hubs (front and rear) can take a 14" rim with decent tires, them I'm golden but I am trying to be mindful to not cause gearing issues or some other prob. Did the spec site show what should be on the rear for rim and tire? Thank you kindly. Quote
linda s Posted Tuesday at 09:52 AM Posted Tuesday at 09:52 AM Well a link to where you saw that. Model number of your truck. Picture? All might help track down what you really need. Linda S Quote
WME Posted Tuesday at 05:48 PM Posted Tuesday at 05:48 PM A 225/50/12.5 tire turns 944 revs per mile, a 185/14 LT turns 819 revs per mile so your going to be working your, no power, engine harder. Steel rims with correct offset and bolt pattern are problematic. Quote
geest31c Posted Tuesday at 08:39 PM Author Posted Tuesday at 08:39 PM Linda, WWE, et al: I am new here. Pic attachment will not function, so here I go: Rig: 1994 Toyota LiteAce/TownAce, Euro Camper CM550037242, 2wd, AT with overdrive. Rear rim is 12.5" with a 225/50R12.5 tire. Front rim is 13" with a 165R13LT. This IS OEM configuration - one configuration among several. However, there are other oem configs for the exact vehicle. For example, my euro camper starts with a standard liteAce truck chassy. There are literally millions of these in a myriad configurations. Some are pickups, some are vans, some are campers - tear off the sheet metal or F glass camper, they are all essentially identical. Curiously, the van config does not use a rear 12.5 wheel at all. Same engine and running gear as my camper, but all 13 or 14" rims. Similarly, some campers just like mine are five bolt or are 14", despite the same engine and running gear, tranny, gear box etc. I can read a simple tire/wheel conversion table - easy peasy. That is not the question. The question is: how do I properly upgrade to a larger rim and tire? I have read a number of old posts where they start out like this: "first thing I did was take off the pos wheels and tires and installed 14" rims with ---- tires." Obviously wheel rotations per minute, wheel well space, gear ratio, etc., etc., factors were considered. Hence, my query to this board. Maybe some mods are required, maybe some tweaks here or there, but this is the land of ingenuity. A tire/wheel conversion chart didn't seem to stop those souls before me and I hope it will not stop me. I am looking for solutions, not "it cant be dones." 12.5" rear wheels is a nogo. Hell, half the flatbed imports I have seen online had the rear 12.5s pulled off before the import ink even dried. My rig, which this site seems impossible to post a picture to, is a townace euro camper with a factory A'm Craft F glass camper shell. 100s are in the US. I just want to get some respectable wheels and tires under my feet. Oh, yeah, btw, you ever tried to buy a 225/50R12.5 tire??? Not a good setup for trips beyond the garage. That's my dilemma, folks. Any thoughts on rational and reasonable solutions would be sincerely appreciated. Quote
linda s Posted Tuesday at 09:38 PM Posted Tuesday at 09:38 PM Found you 14 inch tires that are close to your current wheel diameter. Your current tires are 23.38 diameter. These 14 inch tires are 23.6 and have the load capacity you should really have.

geest31c Posted Tuesday at 11:15 PM Author Posted Tuesday at 11:15 PM Thank you, Linda. Are you thinking that these would be for front and rear? Current rear is quite wide, 225. A 175 is appreciable less. It seems the 225 is not really a truck rated tire and surely no ply near 8 but width does spread the load. Maybe I am overthinking it, as a number of the identical(ish) rigs I have seen show all wheels and tires similar Thoughts? Thank you again. Quote
linda s Posted Wednesday at 04:03 AM Posted Wednesday at 04:03 AM The high load of the Haida tires will more than enough make up for being narrower. Yes your overthinking it. Linda S Quote
geest31c Posted Thursday at 01:48 AM Author Posted Thursday at 01:48 AM Linda, Thank you kindly. You have been most helpful. I am looking forward to the symmetry of 14s all around and the more suitable tires. I appreciate your knowledge and pragmatic thoughts. Quote
