1998 Mercedes e320
Will 245/45/17 fit on a 1998 e320
Hi, I'm new to the thread, thanks for your help. I have a 1998 Mercedes e320 and I just got some new rims for it. It currently has 215/55/16 wheels, I would like to know if I can put a 245/45/17 17x8.5 ET38 on the car. Is it safe to use a spacer to help make the tire fit? Also, if they will fit, what size lug bolts would I need, and what is a good place to order the lug bolts. Thanks again for your help.

you need to separate this into several components and solve them individually,
first. then, as a package.
the ET of 38 should be spot on, plus or minus a few mm or so. no problem
next, it would be desirable that the tire you select retain the same (plus/minus
1-2%) in the tire circumference VERSUS the OE tires of 215/55-16 in order to
maintain odo/speedo accuracy. in addition, the circumference should be the
same for both front and rear tires (more of an issue if staggered). I should
also point out that if the circumference varies too much between front and
rear tires, you potentially lose cruise control function
next, the width of the tire, along with ET38, is important since it may rub the
suspension nut on the upper control arm. natch, tire selection is even more
important now. just because a tire is of X size does not mean that it will be
EXACTLY that compared to another brand/model of the same size. so if you're
pushing the envelope for clearance, be sure to keep this in mind and that it
may be a bit of a gamble
next, you need to assess if you're planning to, or have already performed any
suspension lowering mods to your car. if so, the tire selection will become
even more critical. so now, you will need to eyeball the clearances beneath
the car and extrapolate all the data you've gathered to see if the tires will
clear the 'nut', the wheel liner, and the wheel arch opening. be sure you turn
the steering wheel full lock (both) to observe the shoulders of the tire as it
comes near the aforementioned areas. (generally these critical areas are
more likely to affect the front and not the rear.)
lug bolts - don't know. you've not identified the wheel you're selecting. the
answers here depend on the wheel manufacturer and model
wheel - be sure that the wheel selected is suitable for your MB E320... which
demands 12mm bolt diameter, 12r ball seat, 66.1 hub, 5-112 bolt spacing
spacer - probably not needed based on ET38. that said, some owners look
for that "look" which is based on aesthetics so I'll leave that up to you. in
the rear, again, this is less of a concern though you would need to purchase
extended bolts to account for the added thickness of the spacer. but in the
front, if you insert spacers, you then need to be concerned about clearing
the wheel arch opening else it might scrape under load or when turning

your tire and wheel selections
