How to Choose Electric Dirt Bike Tires for SYKERUNS X5 and X7

Quick answer: Choose electric dirt bike tires by the exact bike model, front or rear position, complete tire specification and intended riding surface. The SYKERUNS X5 has a listed 14-inch front and 12-inch rear wheel setup; the X7 has a 17-inch front and 14-inch rear setup. Matching one diameter is only the first check.

A replacement tire listing can look straightforward until you compare it with the bike in your garage. Is it a rear tire or a pair? Does “14 inch” describe the right wheel? Is the tread intended for the surface you actually ride? This guide helps X5 and X7 owners collect the right information before ordering.

Start with the X5 or X7 model and wheel position

Check the model on your order confirmation, then identify the wheel you are buying for. A shared number in two bikes’ specifications does not make their tires interchangeable.

For example, the X5 front and X7 rear both use a listed 14-inch wheel. That single match does not confirm the same tire width, profile, construction or approved installation position. Shop by model and wheel position together.

If your bike has been modified or already has replacement wheels, tell support before ordering. The standard model specification may no longer describe the installed setup.

Read the complete sidewall marking

Photograph the writing on the tire sidewall rather than sending only a picture of the tread. Tire markings can identify width, aspect ratio, rim diameter, construction, load index and speed rating. Front/rear designations and rotation arrows also matter.

As a general example, a metric marking beginning 120/70 describes a nominal 120 mm width and an aspect ratio of 70 percent. This is a decoding example, not a recommended X5 or X7 tire size. Michelin explains the format in its motorcycle tire markings guide.

Keep the full marking in your message, including any tube-type or tubeless designation. A product photo alone may not show these details. Ask support to confirm the replacement specification against your bike and its installed rim before paying.

Choose tread for the surface you actually use

Tire categories serve different riding conditions. Off-road, road and mixed-use designs are not simply different appearances. Michelin’s tire usage guide explains why intended use is part of tire selection.

Describe your usual surface when asking for a recommendation: a permitted dirt riding area, a private paved practice area, or a combination. A road-focused tread should not be assumed to offer the same suitability on loose ground as an approved off-road tire.

The X5 and X7 electric dirt bikes are sold for recreational off-road use where permitted. A product called a “street tire” describes a tire category; it does not change the bike’s approved use or establish public-road access. Plan tire choice around a riding location where your bike is permitted.

There is no verified X5/X7 comparison here showing a particular tire increases range, improves wet grip by a percentage or lasts a set mileage. Choose based on confirmed fitment and intended use rather than an unsupported performance promise.

What the current SYKERUNS tire listings say

The SYKERUNS accessories collection currently includes two model-specific street-tire listings:

• X5: a listing titled “12" Rear Street Tires for Electric Motorcycles | SYKERUNS X5.” Its description identifies a 12-inch rear street tire. Do not assume it includes a front tire.
• X7: a listing titled “17" Front / 14" Rear Street Tires for Electric Motorcycles | SYKERUNS X7.” Its description references 17-inch front and 14-inch rear street tires. Confirm whether your purchase includes one tire or both before ordering.

Titles and nominal diameters help identify a listing, but the order still needs a complete fitment and contents check. Confirm the supplied tire markings, front/rear position, quantity and whether tubes or other installation items are included. Do not infer package contents from an illustration.

A five-point checklist before buying replacement tires

1. Confirm the bike: X5 or X7, order number, and any wheel changes.
2. Identify the position: front, rear, or a complete matched pair.
3. Record the installed setup: clear sidewall photos and any available wheel or rim identification.
4. Describe your riding: the surface and permitted location where you intend to use the bike.
5. Confirm the order: approved fitment, exact quantity, included items and installation requirements.

You can send SYKERUNS Support a message like this:

I own a SYKERUNS [X5/X7], order [number]. I need a [front/rear/pair] replacement. My current tire markings are [full text], and I have attached sidewall and wheel photos. The wheels are [original/modified]. I ride on [surface] at a permitted location. Please confirm the correct tire specification and exactly what is included.

Have a qualified installer confirm the tire and rim combination. Use the appropriate installation and inflation instructions for the confirmed setup; an online pressure recommendation for another bike is not enough. For routine checks between replacements, see our X5 and X7 maintenance guide.

Electric dirt bike replacement tire FAQs

Are X5 and X7 tire sizes the same?

No. Their listed front/rear wheel setups are 14/12 inches and 17/14 inches respectively. Confirm the complete tire specification, not just a shared diameter.

Is the current X5 street tire listing a front-and-rear set?

The current description identifies a 12-inch rear tire. Confirm contents with support; this guide does not describe it as a complete set.

Can I choose a wider tire for the same wheel?

Do not treat a matching rim diameter as approval for a different size. Michelin recommends keeping the specified dimensions unless an alternative is validated by the vehicle manufacturer. Confirm any change before ordering.

Does fitting street tires make my X5 or X7 road-approved?

No. Tire choice does not change the off-road-use designation of these models or establish permission to ride them on public roads.
