Tires.....Again

[Tone]

Too tall - use the tire calc at miata.net. You'd have to crank the tbars quite a bit to fit em.

I have LT265/75R16 nitto terra grapplers which are 31.54" tall .A small amount of trimming was required. The tires you are looking at are LT285/75R16 which are 32.76" tall. And they are wider. I think that anything bigger than 31.54" is getting real close to major trimming. shawn

I got sick and tired of the Continentals the dealer I bought my VX from put on when they took it in trade. They are loud, hard, and not-too-great grip in heavy snow or mud. And I've only worn through them maybe 40% in 18 months!

So I just ordered new tires for my VX, and will get them put on the VX Saturday morning. Although the Nitto Terra Grapplers could not possibly come more highly recommended on this site, I decided I don't want to do ANY trimming at all, and I do not want an inaccurate speedo, either.

I consulted TireRack.com's reviews & survey results, and decided to go with Goodyear Wrangler Silent Armor tires in stock size. They could not come more highly recommended on their site, either.





Can't wait to put them to the test... I'll post pics so ya'll can decide how they look.

I have the 285/75R16's on my lifted VX and I still had to trim the front fenders a bit. I think the larger width is what requires the most trimming due to the front tires rubbing during turns. You might be able to get away with cranking your torsion bars and trimming, but then the back end is going to look like it's riding too low.

You should consider also what VehiGaz mentioned - larger tires will throw off your speedometer, possibly your ABS(?), and will definitely be harder on your drivetrain and suspension. If you're willing to play that game, you might as well get that lift and the look you are probably wanting.

OK, I have seen a lot of comments about larger tires messing with the speedometer...soooooo, how serious is this? Like when it says you are going 40mph you are actually going 41mph or is it more serious than that?

265/75R16 MTs.

My speedo says 55mph, my GPS says 63mph.

I get 14.5mpg consistently, with city/highway and offroad (hills and gravel) driving.

[nfpgasmask]

Wow, that is *quite* a difference. So you are actually going faster than you think. Thats scary. Is there any way to correct this? Or is it just something you live with once you have bigger tires?

And how come I have never heard of this with other vehicles??? Just curious.

Thanks - Bart

Is that figured after compensating for the difference in tire diameter that threw off your speedometer (odometer) in the first place? I can't figure out how much a difference is made by my 31.5's with no lift on a tank of gas. If you figured out a formula hook a brother up!

BFG T/A KO 265/70R17 (31.6")

Trimming front and back (I have 0 offset on the rims)

I get about a 10% error 60mph at guage, 66mph on GPS.

The bigger tires also throws my TOD a bit wacky on hard accelerations.

I also noticed at Moab that the bigger tires really liked to scrape in the inside wheel wells when on 3-wheels (I'm not lifted )
