Alignment?

Need to take my gal to get an alignment after I replaced all the front end bits, any one have the number for it with 2" spacers on the tires? I went to my local dealer & they didn't know what to do.

 

2” strut spacers? Or wheel spacers?

Any lift at all?

What tire size?

Just have them go in the green range on their equipment. Strut spacers are going to provide worse impact than how you choose to align, if you’re using them. Then watch for abnormal wear over the next several thousand miles.

 

Camber anything from +0.5° to -0.5°, -0.3° is what I'd recommend if possible.

Caster 2.6-2.8° is ideal, but when lifted and without aftermarket upper control arms, you may not achieve it. As much as they can (even if it is just 1.0°), if they can't reach that much positive caster.

Just make sure both sides are even within 0.3° for both camber and caster.

Total toe 0.10-0.15° toe in (.05° - 0.8° per side).

 

Sorry, I thought I put wheel spaces. She's mostly stock out side of the wheel & body spacers, cab to frame, not on the suspension. I have moog upper/lower control arms with moog toe cams.

 

The tires I'm looking at are lt285/75r16's.

 

Too big, don't do it! You'll get a variety of opinions. Personally I'd go 255 if I wanted that much diameter.

 

Can't be too bad, its a 1.73 inch difference between the 2 sizes.

 

Between what two sizes and what two dimensions?

I don't think you are accounting for width and scrub radius.

A 255/85R16 will actually be a larger diameter but you won't rub nearly as much, probably don't need wheel spacers either, but that depends on your offset.

I suggest you watch this. Even if it isn't a 1st Gen, the same principles apply.

 

The specific tire I'm looking at doesn't have a 255 in 16, but this is where I got my numbers. The rims I'm looking at come in a -10 offset. Previously my truck had 33x12.50R18 on & it rubbed real bad, they were on when I bought her, rubbed real bad, sold those currently using 245 on some tacoma 16" rims as a place holder.

LT285/75R16
Dia: 32.83
Wid: 11.26

255/70R17
Dia: 31.10
Wid: 10.24

 

Whether those 285s fit or not is all about offset on those wheels. I’ve got 16x8” wheels with 4.5” backspacing and 285/75/16s. Lifted 2.25” or so in the front with 5100s. Do t run under any normal driving conditions. Haven’t done any hardcore articulation off-road to test, but seem to have good clearance everywhere.

 

Nearly 2" diameter and 1" width added is pretty substantial. The wheel spacers may help you to accomodate the width.

 

Thanks everyone!

 

Take the spacers off and let them do an alignment on it normally, then go home and put the spacers back on if you must. The spacers dont change anything with the alignment. The dealer tech and service guy were probably looking at it with disgust and angst and turned you away due to the potential liability of the front end falling apart.

 

Wheel spacers and that size tire are going to push the tire directly into the fender even worse. He doesnt have enough lift to clear that tire, unless he gets real creative with a sawzall on the fender. The wheel spacers make everything worse on clearance. The further outward you push the center line of the tire away from the pivot point of the hub, the more "swing" it has and the more "stuff" its likely to run into.

 

She had some 33x12.50R18 on her previous & they rubbed a little, but not on the fender.

 

Maybe true on your 2005 DC with fender flares and plastic front bumper.

Probably not true with his 2000 RC with no fender flares or fender trim, and metal bumper.

But fully agree, wheel spacers that large are asking for other disasters to happen. Anything more than an inch is (personal opinion here) not the smartest choice. I personally wouldn't do it, but maybe for someone younger that hasn't seen the nightmare fuel I've seen spacers a handful of times would be more willing to do it.

 

Aka scrub radius
