I think it's close. Look through the threads and get creative with your search. I know it's been talked about a few times but I can't recall the results of that size on their base 2wd model.

I think the wheel on the truck is only 6" wide. That is probably narrow based on the recommendations of tire manufacturers for a 235 wide tire. So that is something else to consider.

I can't think of any threads that you can start with, but a creative search and patience should lead you to the threads. Of course it's not buried in the lifted threads, the threads I'm thinking about are related exactly to the question you asked, so it should be fairly easy to locate. Maybe try using search for the tire size - that may not product too many hits from threads within the last 6 months. They should be on page one of search results.

 

Thanks for the quick reply. Was currently searching the threads and will keep looking. See if I can find out. So far I have seen the WT came with 235 75 R16. Wondering if they sit higher than a z85 2wd or the same?

 

I don't think a W/T is any taller than a base 2wd....I may be wrong.

You may have to find a shorter sidewall tire. Like 235/65-16 for example. That keeps a wider tire and limits the height now. I don't have time now to calculate that size for example...but you get the idea.

 

I don't think a W/T is any taller than a base 2wd....I may be wrong.

nope you are correct on that.

 

I believe there was a member who did 235/85/r16, which is 31.7" roughly....or round to 32 and they were still stock height

 

I ran a 245/75 on stock 16" wheel, 2WD Z85 crew cab. Rub the inner fender on bumpstops and at full turn lock rub the frame.

with the lift the problem was solved.

I think the 235/75 is just a little bit smaller than the 245 so you may experience rub somewhere.

I´m using 225/70 on stock wheels and no rub at all.

*just for your information, my stock Z71 4x4 with stock tires and wheels rub the frame at full lock too. so I guess GM decided that it´s not a big issue.

 

According to the "online tire calculators" 245/75 R16 is 30.5 x 9.65
so not significantly different in height to 235 75 R16 (29.9 x 9.25)
however the width may decrease the rub on them. I would love to lift my dads 2wd but he is just not into that....lol

If it does rub I will post here to alert other members. I am hoping is not to much. Perhaps something my dad wont notice at his age

 

No way is a 32" tire fitting on a stock 2wd Z85 without any rubbing concerns. That's the diameter o my 1.5" lifted 4x4. It barely fit when the truck was just level with stock rear height.

Discount tire should be able to test fit the tire for you to ensure it fits fine. The shop may also warn you that the wheels are narrow for a 235 width. I'm not sure if a 6" wide wheel is the approved width (without looking up the specific tire) for a 235/75-16 tire. My 4x4 Z85 comes standard with 6.5" wide wheels and I think the 2wd versions are more narrow. The manufacturer sticker located on the driver side door jamb will specify the wheel width of your truck.

A 235/75-16 sounds like a really big tire on a W/T model. Not saying it's not possible, but it doesn't sound right to me as that is the most basic of basic you get.
The 16" wheels came out in 2009 to fit the larger brakes.....I thought most of the trucks went to a 70 series tire with 16" wheels, keeping nearly the same diameter while offering a larger hole.

Z71's can't be compared to 2wd Z85, different wheel size, offset and fitment.

 

According to this 32s fit...minor trimming but fit. Took me a while to track that thread down but I knew we both commented on it when it was posted

Oh man, I remember that thread.

 

I by no means recommend that big with no lift but it can be done. I want some gap in there personally. Unless you are super low gap is good. I have the smaxx lift and was kind curious how that size would look in mine. Might see if I can mock one up in there when I am ready for tires.

 

Did some research under cars.com and found out that some 2wd in 2012 did come out with 235/75R16 but it was an optional package under the SLE1.

Cool. Maybe it was only the Z71 pacakage.

they used to be /75-16 but also had a /70-17 (same size overall).

Just double check the wheel width. Or just have the shop install one tire as a test to make sure it clears the front components when steering. Each of the wheel width sizes have a different backspace, but most are overall similar. If that is too deep the tire sits inward and could rub with the wider tire. Probably fine - but nice to be aware of posibaliites before the purchase. Americas Tire/Discount Tire is really good about helping and ensuring the tire they sell will fit the vehicle. Not something people get with an internet sale for sure.

Let us know how it goes.

 

Most definitely will let you guys know. I'll check the door sticker for wheel width and have discount tire test fit them. They are my favorite tire shop, especially with warranty honoring.

 

And they fit...test fitted by discount tire and drove it with no rubbing what so ever.

Hooray!!

thanks for sharing.

 

No problem! Next is to tune his truck to recalibrate tires.

 

What was the stock size of the vehicle.....

 

215 75 r16

 

Glad that worked for you

 

You're only 4% off then.

You will be traveling around 73mph when your dash reflects 70. It's 4% off everywhere, not 3mph off everywhere. Less inaccurate at lower speeds I mean.

 

I did see that on a site tire calculator and observed how its affected by percentage. Not too bad but the old man still wants to tune his truck lol. Truck doesnt seem to struggle with new tires but i did see on his glove compartment he is equipped with 3.73 gears unlike my z85 4wd with 3.43s. Not to mention his 2012 with 3.7L vs 3.5l

 

Great to see that you got the tires!

Just one more test for the good of this comunity.
is it possible for you to see if the tires rub the inner fender at full front axle flex? I did that driving really fast on a turn on highway and then inspected the inner fender, I found marks (with the 245/75/16). other way maybe is taking the truck to a ditch and try to flex it.

If you confirm no rub at all after this test, then its official you had found the max tire size without rub for this trucks.

 

Will do. Dad works away but he should be coming down agAin this weekend.

 

So I called my dad over and had him test drive the truck on highway. Alignment has been done on it and no rubbing. Truck handles well! Tune is still pending although he claims the performance does not show a noticeable decrease. Maybe it's due to the 3.73 gears; kind off interesting how it came with those gears and only 215 75 r16 stock wheels.

 

The size increase isn't super dramatic - not too much performance loss should be experienced. Just 'off the line' performance' maybe.
